摘要
复杂地层条件下,为了确定大型LNG储罐桩基的长度,基于部分超前钻地层信息,采用理正三维地质软件结合Surfer软件,使用克里金插值法对场区中等风化岩面深度进行计算。这种方法可相对准确地计算所有桩的长度,进而可提前统计总的桩基工程量和开展桩基的预制工作,对复杂地层条件下桩基设计和现场桩基施工具有指导意义。
Under the complicated stratum conditions,in order to determine the pile length of large LNG storage tanks,based on some advanced drilling stratigraphic information,Li Zheng 3D geological software combined with the Surfer software and Kriging interpolation method were used to calculate depth of medium weathered rock. The method can calculate the length of all piles relatively accurately. Furthermore,the total amount of piles can be get and the prefabrication work can be carried out in advance. The method is of guiding significance for the design and construction of pile foundation in complicated stratum conditions.
