高层建筑基础形式通常分为筏板基础、桩筏基础、桩基础以及交叉梁式基础等。也可以先进行地基处理,使处理后的地基满足设计要求再进行基础设计。以下就筏板基础、桩(或桩筏)基础、地基处理三种情况进行叙述分析。一、筏板基础方案一般情况下地质情况良好,满足承载力及变形要求时,首选筏板基础,相对其它基础形式而言,筏板基础施工工序简单,较为经济合理。在地基承载力不足的情况下,可以考虑对地基进行深度修正。当结构为主楼裙楼一体结构,对主楼地基承载力进行修正时,将裙楼基 The basic form of high-rise buildings are usually divided into raft foundation, piled raft foundation, pile foundation and cross-beam foundation. Can also be the first foundation treatment, so that the treated foundation to meet the design requirements of the basic design. The following raft foundation, pile (or piled raft) foundation, foundation treatment of the three cases described and analyzed. First, the raft foundation program Under normal circumstances, the geological conditions are good, to meet the bearing capacity and deformation requirements, the preferred raft foundation, relative to other basic forms, the raft foundation construction process is simple, more economical and reasonable. In the case of insufficient foundation bearing capacity, the ground can be considered for depth correction. When the structure of the main building podium one structure, bearing capacity of the main building foundation to be amended, the podium foundation
