The plate anchor has been commonly used to stabilize the sheet pile walls, bridge abutments, transmission towers, and mooring systems by providing uplift resistance. This study included a series of numerical simulations to investigate the uplift capacity of plate anchors and the failure mechanisms of overburden soil using the elastoplastic finite element method. Numerical modeling was verified using the model test results from the literature and showed good agreement. Numerical simulations in this study considered different soil internal friction angles, dilation angles, and embedment ratios (the ratio of embedment depth H to plate anchor width B ). The overburden soil was classified as shallow embedment and deep embedment based on different failure mechanisms. The threshold value of embedment ratio for the shallow embedment and deep embedment increased as soil internal angle and dilation angle increased. During the uplift of the plate anchor, two straight slip surfaces gradually extended from the edge of the plate anchor to the surface of overburden soil at shallow embedment, while two-segment polylines occurred with a rigid core inside at deep embedment. The uplift capacity factor increased as the soil internal angle, dilation angle, and embedment ratio increased. To reflect the practical influence of dilation angle, an internal friction angle reduction method was introduced to modify Kumar and Kouzer’s method. The calculated uplift capacity factor from the modified Kumar and Kouzer’s method well matched the calculated from the numerical simulations.

A BIM-GIS based visual management technology of super tall building construction process is proposed to improve the quality of super tall building construction management and enhance the visual management effect. First, BIM technology is introduced to realize the establishment of the 3D model of the building structure of the building project based on Revit 2015 software. According to the construction project of the super high-rise building, it is divided into civil model and steel structure model to complete the construction modeling of the super high-rise building. Then, the BIM model is converted into the 3D GIS scene model. Finally, the construction simulation function design and database design are carried out to realize the visual management of the construction process of the super tall building. The experimental results show that the method applied in the construction process can make the project participants understand the whole construction process more clearly, and it can monitor and manage the project progress in real time, which can better simulate the construction process and realize the visual management function.

In order to study the influence of external packed walls on the seismic performance of prefabricated shear walls, a 1:3 scale prefabricated shear wall specimen with two layers of prefabricated (PC) packed walls was designed and manufactured. The deformation form, maximum floor acceleration, maximum relative floor displacement and interfloor displacement Angle of shear wall structure under different seismic intensities were obtained by shaking table test, and the mechanical performance of the specimen was further studied by finite element simulation method. The results show that the prefabricated filled wall set in Y direction provides a certain lateral stiffness to the shear wall structure and reduces the structural deformation in this direction. It is suggested to consider its influence on the overall stiffness of the structure in the design of the structure. The wall cracks are mainly distributed in the parts of connecting beams, the corners of door and window openings and the parts of wall limbs, and eventually the bearing capacity is lost due to the concrete fracturing in the parts of wall limbs.

开发了可视化土工模型试验箱及模拟隧道开挖地层损失的水囊装置,考虑隧道埋深、隧道与挡土结构水平距离及隧道开挖体积损失3个因素开展了多参数影响模型试验,通过粒子图像测速技术获取填料位移,对地层变形、滑移面演化与地表沉降规律进行分析.结果表明:隧道开挖使隧道上方土体形成三角形集中下沉区域,下沉量随隧道开挖地层损失的增大而增大,地层沉降影响区域随隧道埋深的增大而逐渐扩大,当开挖距离较小时,隧道上方两侧地层向挡墙一侧偏移的现象较为显著.随开挖距离增加,隧道靠近挡土墙一侧滑移面角度变化程度不大,远离挡土结构一侧滑移面角度增大.

Landslide stability analysis is the basement of landslide research. To study the influence of water on reservoir landslide stability, taking a landslide for example in a hydroelectric power station based on detailed field investigation and reservoir operation data, the geological conditions, reservoir and rainfall were considered, the slope failure pattern under natural state and rain state were simulated with Mohr-Coulomb criterion after an numerical three-dimensional model established by the fast Lagrange analysis of continua in 3-dunebsion. A simulation was made for the sliding direction under limit equilibrium situation. The change laws of stability were analyzed under self-gravity, rainfall and reservoir water fluctuation. The distribution characteristics of plastic deformation, displacement and potential sliding surface inside slope were intuitively showed under different conditions. From the point of instability mechanism, water is one of the important factors inducing landslide instability. The key block is suddenly broken with shear rupture that triggers landslide. It offers a reliable basis for both prediction of second landslide induced by rainfall and disaster prevention.

In this paper,the context of circular economy of green marketing on the real estate industry to conduct in-depth to explore further.Green Marketing in the current basis of the status quo,pointing out that the existence of the current green marketing,such as homogenization of serious deficiencies.At the same time, the existing green marketing of the real estate industry has not really guide the concept of green consumption of the whole society.Green marketing is just to stay on the surface,and not permeate the operation of processes across the enterprise.Based on the impact of circular economy on the real estate industry analysis this article put forward the demand to create green consumption,pay attention to green real estate information,establish a green corporate culture and related green 4P portfolio strategy to improve the response.It illustrates green marketing effectiveness of the actual cases of two development of ST real estate.

建筑企业文化与一般企业文化有很多的共性,与一般企业文化相比,又具有自己的特色。建筑企业文化以价值观为主线,以企业精神、企业目标等为主要内容,贯穿于建筑企业生产经营的各个环节,从而构成建筑企业文化体系。在建筑企业实际运行的过程中,企业文化建设出现了一些误区或偏差。本文给出了建筑企业文化构建思路。
