平板式筏基柱下冲切计算的调整

Adjustment of Calculating Punching under Columns for Flat Plate Type Raft Foundations

文章主要通过分析新旧基础规范在平板式筏基边柱柱下冲切计算方面的变化,进而为筏板基础冲切设计找到了一个新的办法,同时也发现了一些新规律。通过工程实例计算数据的对比,进一步印证文章总结的规律,并为今后的实际应用提供了有益的启示。

In the paper, a new method and some new laws for designing punching raft foundations are found out by ana- lyzing the changes of calculating punching under side columns for flat plate type raft foundations with old and new versions of foundation specifications. Moreover, the laws are confirmed by comparing the calculating data of an engineering example, which is beneficial for the practical applications in future.
