作用于挡墙上的水平冻胀力是季节冻土区挡土墙设计的主要荷载。本文介绍哈尔滨郊区万家冻土试验场全约束状态的层迭对顶式模型挡土墙的设计及用荷重传感器、静态应变仪测试挡墙水平冻胀力的方法。
The horizontal frost heave force acting on the retaining wall is the main load of the retaining wall design in the seasonal frozen soil area. This paper introduces the design of a fully constrained laminated top-of-the-wall retaining wall in the subproject of the Wanjia Permafrost Experimental Station in Harbin, and the method of testing the horizontal frost heaving force of the retaining wall with load sensors and static strain gauges.
