摘要
为了掌握采空区建筑场地的建筑适宜性,基于地震勘察、地质钻探、残余沉降分析等方法的综合运用,结合本地实际经验,探讨了该场地作为建筑用地的可行性,研究了采空区塌陷盆地残余沉降值计算方法.结果表明现研究区场地的残余下沉量最大值约200 mm,未来的地表沉降变形将以残余变形为主,其地表移动变形的活跃期已经结束.本文分析为同类工程场地问题的评价提供了参考.
In order to make clear the suitability of construction site over goaf areas,we discuss the feasibility of such building site and study the calculation method for residual ground subsidence of the collapse basin based on seismography,geological drilling,residual ground subsidence,and the local experience.The results show that the maximum residual subsidence is about 200 mm,the active period of surface deformation has finished,indicating that the subsidence deformation will mainly be the residual deformation ...
