| 摘 要： | 以地球物理学基本理论为指导,根据地球重力场的特点,探讨了基坑工程坑壁侧压力及应力来源(即水平地应力),指出地应力产生的主要原因在于重力(即地心引力)。重力不仅可以产生竖向地应力,而且还可产生水平地应力。文章给出了重力所致水平地应力的表达方式,并提出了基坑工程坑壁侧压力及水平应力计算的一种新方法,找出了基坑工程坑壁水平应力的竖向分布规律与实际情况基本吻合。 |
| 关 键 词： | 基坑工程 坑壁侧压力 计算 地应力 水平地应力 计算方法 |

| Abstract: | According to the basic theory of geophysics and characteristics of gravity field of the earth,the authors probe into the source of lateral pressure and stress of pit wall in foundation pit engineering(i.e.horizontal crustal stress),and point out that the main cause of crustal stress is the gravity(i.e.the terrestrial gravity),which can not only produce vertical stress,but also horizontal stress.This paper presents an express mode for horizontal crustal stress by gravity,puts forward a new calculation method for the lateral pressure and horizontal crustal stress of pit wall in foundation pit engineering,and concludes that the vertical dispersion law of horizontal crustal stress of pit wall in foundation pit engineering tallies with the real conditions. |
| Keywords: | foundation pit engineering lateral pressure of pit wall calculation crustal stress horizontal crustal stress calculation method |
