剪力墙结构在山地建筑中的应用

Application of shear wall structure in mountain building

随着城市化进程的发展,城市建设用地越来越紧张,原来不便于开发的郊区山地被用来开发建设。从山间别墅到普通住宅,从框架结构到剪力墙结构,山地建筑在确定接地方式、计算嵌固端、抗震不利地段地震放大系数等方面存在诸多难点。通过介绍某建筑地下室一侧临空,另外三侧挡土,设置结构空腔解决基础高差的做法,地震作用按实际嵌固端分别在正负零和基底进行包络计算。并对采用灌注桩-筏板基础与地基处理-设置结构空腔-筏板基础两种基础形式进行了技术经济比较,供类似项目参考使用。

With the development of urbanization,urban construction land is becoming more and more tense,and suburban mountain areas that were not convenient for development were used for development and construction.From mountain villas to ordinary houses,from frame structures to shear wall structures,mountain buildings have many difficulties in determining grounding methods,calculating embedded ends,and seismic amplification factors in unfavorable areas.This article introduced the method of setting up structural cavities to solve the foundation height difference in the basement of a building with one side empty and the other three sides retaining soil.The seismic action was calculated at the positive and negative zero and base respectively according to the actual embedded end.In addition,a technical and economic comparison of the two foundation forms using cast-in-place pile-raft foundation and foundation treatment-setting structural cavity-raft foundation was made for reference for similar projects.
