近年来，由于强夯法施工范围广，在施工现场附近不可避免地会遇到破损的古木结构建筑。本文以山西五台山的南禅寺大殿模型为研究对象，通过数值模拟的方式进行研究强夯振动对周围古建筑木结构建筑物的影响。研究结果表明：强夯振动对木结构柱架层破坏较大且加速度锐减快，测到木结构各部件加速度峰值说明木结构各部件的减振作用，并且在古建筑木结构建筑物近点进行强夯会对结构造成的影响较大。

In order to analyze the seismic response of local mountain terrain and make up for the lack of relevant research on SV wave incidence, a finite element model of local mountain terrain is established in this paper.The constitutive model of soil is linear elastic and site conditions are isotropic and homogeneous.The domain of soil calculation is 400m×200m, The radius of semi-circular mountainous terrain is 50m.The results show that when SV wave is incident in local mountain terrain, the reflected waves and scattered waves generated by the ground surface superimpose each other in the mountainous terrain, and the interaction law is more complex; when SV wave is incident vertically, the displacement amplitudes are symmetrically distributed, the amplitude of seismic response at each point in the horizontal direction is larger than that in the vertical direction; when SV wave is incident for an angle, the change of wave shape due to the tending to a critical angle makes the law of earthquake motion in mountain area more complicated: When the local mountain terrain’s height and medium change, the amplitude’s change of ground displacement does not monotonic, it fluctuates in a certain range, the frequency of seismic wave also has an important influence on the amplitude of mountain displacement.

Energy saving and structural integration is a green exterior wall technology vigorously promoted in my country.In order to explore whether there will be uncoordinated shedding and the dangerous position that it is easy to peel off during use, the finite element model of the overall structure and detail components of the shear wall with FS external formwork cast-in-place concrete composite insulation system is established by ANSYS software to analyze the force and deformation of the integrated wall in the process of use.The research results show that the deformation between most of the structural members and the integrated outer formwork is small and coordinated.With the increase of building storey height, the internal and external corners are the most likely locations for uncoordinated deformation, and the deformation between them is more coordinated when the thickness of the structural wall increases.
