摘要

摘要: 提出高层建筑桩箱(筏)基础新的沉降计算方法——发展的简易理论法。此法简单、方便,且可手算；计算参数容易确定；计算结果不需乘以桩基沉降修正系数；能反映建筑物荷载与沉降的非线性关系；计算沉降量与实测推算值相当接近；该方法可适用于其他软土地基。这个方法可以作为国家标准《建筑地基基础设计规范》(GB 50007—2002) 桩侧考虑剪应力的沉降计算模式的补充。

Abstract: A new method——the simplified theoretical method for calculating the settlement of piled box raft foundations for high buildings is proposed. This method is simple and convenient and can be calculated manually. Its calculated parameters are easy to be determined. The calculated value of settlement does not need the empirical coefficient for the depth modification. This method can show the nonlinear relation between the settlement and the load of the buildings. The comparison between the calculated and extrapolated measured values of the final settlement shows that the proposed method is feasible in Shanghai as well as in other cities. It can be supplement as the national standard "Code for design of building foundation" (GB50007-2002) considering the settlement calculation mode in shear stress of pile side.
