长短组合桩工程特性的数值模拟研究

以江苏省常州市某拟建新厂区软弱地基上的长短桩复合地基为背景，在现场单桩静载试验的基础上，运用ABAQUS有限元软件对长短桩复合地基的承载性能进行了数值模拟，并将现场试验和数值模拟结果进行对比。结果表明:数值模拟结果与现场单桩静载试验结果十分接近，验证了ABAQUS建模的合理性和可行性。

Study on Numerical Simulation of Engineering Characteristics of Long-short Piles

Based on the long-short pile composite foundation on soft foundation of a proposed new plant site in Changzhou, Jiangsu Province, the bearing capacity of long-short-pile composite foundation is simulated by using the finite element software ABAQUS based on the field single pile static loading test. And the results of field test and numerical simulation are compared. The results show that the single pile static load test results and the simulation results are very close to and the rationality and feasibility of ABAQUS modeling are verified.
