Pile foundation is a basic form widely used in modern construction , is closely related to its design and geotechnical conditions ; rational design , construction quality is good or bad determines whether the building safe and economical ; determination of the bearing capacity an important and complex issue . Ganzhou is located in Nanling , Wuyi Zhu Guang three mountains handover region growing with the expansion of urban scale and high-rise buildings , pile in the increasingly widespread application of the central city of Ganzhou . Its pile foundation design and construction are more complex , there is a lot of further study and resolve the problem requires a combination of local conditions . This article has some useful exploration of some of these issues , specific work includes the following aspects: 1 , by the extensive collection, collation , and summarizes the existing engineering survey data and test data , the the Ganzhou city center area is divided into three zones : the Hetao old town , Zhang Jiang New District and along the river area . On this basis , the District of pile foundation Selection , different regions , different architectural reasonable pile foundation type . In order to capture the overall center of Ganzhou city Selection of Pile Foundation law , construction projects , particularly on regional planning , design a reference . Empirical formula for the bridge , a comparative study of pile foundation , the establishment of a high- strain method , static load bearing capacity of the two methods of test method and specification formula to determine the relationship between . Several pile bearing capacity test methods , including static load test, dynamic load test and pile testing of newly developed self-balancing law , from test principle , test methods , and results analysis, and the advantages and disadvantages of summarized . Finally , the specific operating procedures as well as self- balance method of Ganzhou City Government Center North Main Building engineering test pile test was introduced last calculated ultimate bearing capacity of self-balancing test pile .
