| 摘 要： | 由于对岩土本构关系认知上的差异，人们提出了各种各样的基坑坑壁土压力计算方法，这些方法对推动岩土力学的发展起到了许多积极作用。客观上讲，现有的这些基坑坑壁土压力计算方法没有一个能够非常真实、非常准确地反映基坑坑壁土压力的变化。以地心引力为依据，结合大量的基坑坑壁土压力实测数据，提出了一种基于引力场的基坑坑壁土压力计算方法。给出了相应的计算公式和应用实例。

| Abstract: | Due to the difference of cognizing relations of rock structure, all kinds of methods of the foundation pit pit-wall soil pressure are put forward, which has impelled the development of rock mechanics greatly. Impersonally speaking, none of these calculation methods exiting now can reflect the change of the foundation pit pit-wall soil pressure very truly and exactly. According to centrifugal force, combined with plentiful truly measured data of the foundation pit pit-wall soil pressure, a calculation method of the foundation pit pit-wall soil pressure based on gravitational field is put forward. Corresponding calculation formula and application examples are offered. |
