摘要
运用自平衡法对南宁快环立交工程桩基进行承载力检测。结合该工程实例对平衡点的计算、荷载箱的安装、自平衡法试验操作过程、压力注浆等施工工艺、等效转换原理及过程做了详细介绍。
The self-balancing method is used to test the bearing capacity of pile foundation of Nanning fast ring road overpass.Combined with the engineering example,the calculation of balance point,the installation of load box,the test operation process of self-balance method,the construction technology of pressure grouting,the principle of equivalent conversion and the process are introduced in detail.
