摘要
根据均布荷载作用下地基沉降分布特性,提出一种新型墙柱结合地基处理方法。通过调节墙式加固体和柱状加固体深度和位置,实现提高地基承载力,降低基础总体沉降和控制基础的不均匀沉降。在相同外围墙式加固体条件下,通过改变桩长和位置布置,设计了五组模型实验方案,并利用自制加载系统模拟均布荷载进行载荷试验。根据沉降分布曲线分析,得到了有益的结论,可供建设与设计单位参考。
Based on the property of ground settlement distribution under uniformly distributed vertical load ,here ,a new type composite foundation with wall-shaped and columniform improvement was put forward .By adjusting the depth and position of wall-shaped and columniform improvement bodies , the foundation bearing capacity was improved , the total ground settlement was reduced and the ground differential settlement was put under control .By adopting the same wall-shaped improvement bodies ,5 groups of model tests with different combination of columniform improvement lengths and arrangements were conducted ,meanwhile the load tests were performed by using self-made loading system to simulate the uniformly distributed vertical load .By analyzing the curves of settlement distribution of the tests ,some beneficial results were obtained .These results will provide valuable references to the construction and design of similar projects .
