摘要: 沉降计算是地基验算的重要组成部分，当遇到软弱下卧层时必须做沉降验算，但是，筏板基础的沉降设计通常偏于保守．分析规范法计算出的筏板沉降与实测量的沉降数量差别，仅为包头地区高层筏板基础设计提供参考．

Abstract: Settlement calculation is an important part of the foundation checking，which must be carried out when the soft substratum appears．However ， the design of raft foundation settlement often tends to be conservative． Herein，the differences of a raft between the calculated settlements and the measured settlements were analyzed in order to provide a reference for the design of raft foundation for the high-rise buildings in Baotou district．
