漕河渡槽灌注桩承载力与静载试验比较

Comparison of Design Bearing Capacity and Site Static Load Test of the Cast-in-place Piles in Caohe Aqueduct

漕河渡槽槽身段采用灌注桩基础,桩基进入弱风化岩石0.5m,按纯端承桩计算桩基承载力。采用桩基静载试验检测桩基承载力,试验结果表明,漕河渡槽桩基承载力达到设计要求。

The cast-in-place piles foundation is adopted in the Caohe aqueduct body. There is 0.5 meter of the piles foun- dation entering into the weak weathered rock, the bearing capacity of the piles foundation is calculated according to point bearing pile. The static load test is adopted to check the the beating capacity of the cast-in-place pile foundation, the test results show that the beating capacity of pile foundation in Caohe aqueduct meet the design requirements.
