摘要
为完善组合桩型复合地基设计理论,以单一桩型复合地基计算方法为基础,给出了其承载力和沉降量计算方法,提出了静载试验结果的尺寸修正方法,并与测试结果进行了验证。结果表明:经修正后,承压板下组合桩型复合地基承载力试验值与采用本文公式所得计算值吻合;采用桩间土的压缩模量乘以承载力的提高幅值,所得复合压缩模量计算组合桩型复合地基,最终沉降满足工程要求。
In order to perfect the design theory, on the basis of the calculating method for the single kind pile composite foundation and the test for the combined pile composite foundation, the simplified calculating formula of bearing capacity and settlement for combined pile composite foundation is derived; and the measurement-revising method of the plate loading test value is presented. The results show that the revised test value of the bearing capacity of combined pile composite foundation under the loading plate is fit for the value calculated with the paper's formulas, and it meets the engineering demands that the final settlement is calculated with the proposed method, in which the improving rate of compression modulus is equal to the one of bearing capacity.
