在黑方台地区由于常年灌溉导致地下水位上升,诱发了大量的滑坡.根据对黑方台野狐沟左岸滑坡的地质构造、地层岩性、地形地貌、水文地质和物理地质现象的现场调研,分析野狐沟沟口左岸7#滑坡随着时间的推移,沟深加深,基岩出露厚度增大,对滑坡规模、滑坡类型和坡体变形的规律性影响.利用Midas/GTS软件进行数值模拟计算,分析坡体位移、应变的变化规律,总结了野狐沟沟口左岸7#滑坡演化规律,对于更好的认识野狐沟斜坡地质灾害,滑坡防治、固沟护台、保护农田耕地有积极的作用.

黑方台地区滑坡频发,对公路、输电线路等基础措施、周围村庄及村民财产安全和人身安了巨大威胁.GTS/Midas 岩土工程数值模拟软件,有可视化界面及强大的建模功能,因此,能够很好地模拟黄土边坡的变形破坏过程.以黑方台焦家崖头滑坡为例,结合野外实测地质资料,运用GTS/Midas建立边坡二维模型,采用强度折减法(SRM)及极限平衡法(SAM)分别对其进行计算分析并比较,得到边坡的最大剪应力、最大剪应变在边坡岩土体中的分布状况及安全系数;最大剪应变面位置,即潜在滑面,与实际滑面基本相近.

This paper introduces the development of a high-performance cluster and its features,and presents a popular high-performance cluster job management system.The TORQUE job management system structure and the process of job submission are analysed through an example for MPI parallel programs for nano-material analysis to run on high-performance clusters..

The authors introduce the fundamental principle and ordinary rnethod of access and control to AutoCAD in Delphi,which can on one hand realize the concrete functions of creating,selecting,editting and managing AutoCAD entities and on the other hand solve the problem of interface with AutoCAD in the secondary development of AutoCAD with Delphi.
