一、概论在土木工程和港口码头建设中往往大量采用桩基础。但是,如何确定桩的承载力以及检验工程桩的质量,是工程界十分关心的问题。现在一般都是通过静载试验和动测法等方法来进行试桩的。桩的承载力包括桩身的结构承载力和地基对桩的支承力。因此,桩的完整性试验和承载力试验是同等重要的。但是,静载试验却把这两方面的问题混在一起来解答,一般 First, an overview In the construction of civil engineering and port terminals are often extensive use of pile foundation. However, how to determine the bearing capacity of piles and to check the quality of engineering piles is a very concern for the engineering community. Now generally through static load test and dynamic test method to test the pile. The bearing capacity of the pile includes the structural bearing capacity of the pile body and the supporting force of the foundation to the pile. Therefore, the pile integrity test and the bearing capacity test are equally important. However, the static load test mixes the two aspects of the problem to answer, in general
