摘　　要：结合工程实测结果,提出按侧阻抛物线分布假定计算复合地基计算的思路,按有效桩长计算确定抛物线形态,运用弹性力学方法推导了计算公式,并通过算例与工程实测进行对比验证。结果表明,按文章方法计算桩土荷载分担和桩身侧阻曲线,与实测结果符合较好,计算方法可行,能够满足工程需要,可供类似工程研究与设计参考。Based on the test results and the assumption of lateral resistance parabola distribution, the method of calculation of composite foundation, determining parabola form based on the effective pile length and de ducing formula by elasticity mechanics, was put forward. The comparison results show that the method to the loadsharing of pile and soil, and the curve of pile side resistance coincides well with the measured results, and that the calculation method meets the requirements for the engineering design and can be used as the ref erence for the related projects.
