【摘要】 随着经济的发展,高层和大型建筑物越来越多,建筑物的深基坑开挖的深度和规模也越来越大.为保证基坑开挖的安全及降低工程的造价,深基坑施工中的变形监测已经越来越受到人们的重视.现行规范中规定的监测方法、精度和监测的内容已不能适应深基坑施工的要求.文中以今晚报大厦深基坑施工中的变形监测为例,介绍变形监测的一些进展.更多还原

【Abstract】 Along with the economic development, high buildings and great structuresare becoming more and more, the depth and dimensions of excavating fundations arebecoming larger and larger. In order to ensure the safety in fundation excavating and toreduce civil engineering cost, the deformation moaitoring during deep fundation con-struction is now attached even more importance to by people. Currently stipulatedmonitoring methods, accuracy and items in coustruct specification can now not satistythe demands in the deep fundation excavating. In this paper, the authors take the de-formation monitoring performed during the deep fundation construction of the "Jin WanBao Building’ as an example to introduce some progress in deformation monitoring.更多还原
