目前,桩基础在我国应用较为广泛,特别是沿海及地质情况较差的地区。由于这些地区特殊的地质条件,天然地基无法满足设计承载力要求,只能通过地基处理和采用深基础的方法来解决。对于大型的工业建筑,由于对地基承载力的要求较高,因此做一般的地基处理也无法满足设计要求,而且造价 At present, pile foundation is widely used in our country, especially in the coastal area and poor geological conditions. Due to the special geological conditions in these areas, the natural foundation can not meet the design capacity requirements and can only be solved by foundation treatment and deep foundations. For large-scale industrial buildings, due to the higher requirements of the bearing capacity of the foundation, so do the general foundation treatment can not meet the design requirements, and the cost
