随着我国社会经济快速发展,城市内高层建筑和立交桥建设发展迅速,为满足这些建筑物地基承载力和降低桩的扭曲变形设计要求,多采用群桩基础,然而群桩基础的沉降问题一直是建筑行业的研究问题。群桩基础的沉降与建筑地基土质状况和桩基与其上层建筑物结构有密切联系。群桩基础沉降计算是桩基计算中的一个研究难点,本文就是理清群桩沉降的构成基础上,对群桩沉降计算过程中的几个问题进行了讨论,并提出相应改进措施。
With the rapid socio-economic development of our country, the construction of high-rise buildings and overpasses in the city is developing rapidly. In order to meet the design requirements for the foundation bearing capacity of these buildings and to reduce the distortion of the pile, the group pile foundation is mostly used. However, the settlement of pile foundation has always been Construction industry research issues. The settlement of pile foundation and the soil condition of the foundation and the structure of pile foundation are closely related to the structure of the superstructure. Pile foundation settlement calculation is one of the difficulties in the calculation of pile foundation. Based on the comprehension of the settlement of pile groups, this paper discusses some problems in settlement calculation of pile groups and puts forward corresponding improvement measures.
