To the State Key Highway Rongcheng to Wuhai line Qingdao Section of highway two bridge pile foundation of single pile bearing capacity as a research topic , Rong Wu line is part of the North China platform , the starting point is located in the northern section of Yishu fault zone , is a glue North Fault uplift and Weifang rift zone along geological data , representative , thick soft soil distribution K6 703 bridge No. 4 station K8 778 bridge No. 5 station test research pile vertical Bearing changes . Test site test pile load test , and buried in the cross section of each test pile reinforced stress meter reflects the pressure of the axial force and pile end data processing and analysis of the test data , for different types actual bearing capacity of the pile length pile for pile foundation or soil to destroy data , to determine the relationship between the ultimate bearing capacity and settlement of pile foundation for the optimization of the design of the project to provide a reliable basis . Displacement of the lower part of the pile foundation , pile lateral friction resistance consequent increase further play pile at the bottom of the resistance , when the maximum pile foundation lateral friction resistance , the load will the end of pile foundation is exposed , if loads continue to increase , then , due to the displacement of the pile foundation has reached the maximum lateral friction resistance at this time has been largely or even most of it will go to the pile foundation ends , side Ministry by the force of a great pile foundation problem arises .
