2、高大的建 筑能在地质条件不能满足浅基础的情况下得以解决。 桩基础对于高层建筑的高荷 载，能有较好的承载能力，而且沉降问题也能得到减缓，在高大建筑，桥梁，地 下隧道，水利水电工程中应用广泛，能很好地满足现代建筑的要求。 本设计是先通过地质勘查，了解建筑物情况，然后决定桩形以及尺寸，确定 复合基桩竖向承载力设计值，沉降计算，桩顶作用效应验算。 关键词:浅基础 深基础 复合基桩竖向承载力设计值 沉降计算 桩顶作用效应验 算 ii AbstractAbstract More than two thousand years in China is inseparable from the pile fo

3、undation, the old pile foundation to now high-rise buildings of the new type of pile foundation and this foundation form has been in use ever since, pile foundation is the most commonly used in two, respectively is deep foundation and shallow. When the geological conditions are bad, whether the stre

4、ngth of the foundation, deformation, stability can not meet the requirements of the foundation, on the choice of deep foundation. The pile foundation can transfer the load of the upper part to the ground floor hard soil by the pile, so that the tall building can be solved in the case of the geologic

5、al conditions which can not meet the shallow foundation Pile foundation for the high load of high-rise buildings, has good carrying capacity, and settlement of the issues can be slow, in tall buildings, bridges, tunnels, water conservancy and hydropower engineering widely used, can well meet the req

6、uirements of modern architecture. The design is first through geological exploration, understand the situation of the building, and decide the pile shape and size, determine the composite pile vertical bearing capacity design value, the settlement calculation and checking the effect on pile top. Keywords: design value of pile top settlement effect checking calculation of bearing capacity of shallow foundation and deep foundation composite vertical pile 湖北工业大学工程技术学院本科毕业设计 目目 录录 摘
