关于桩基承载力自平衡测试法荷载箱的探讨

his paper introduces the principles about self-balanced test method for pile bearing capacity, and some problems exist in the load cell. Also it shows advantage of the Nang-shi load cell. At the same time, deep plate loading test with self-balanced method, Tong Mo static load test, and measuring pile bearing capacity by self-balanced system with loading on pile top are introduced on the base of principle about self-balanced method. At last it points out the advantages and shortcomings of each load cell, as well as some ideas about load cell improvement for self-balanced test method.
