Abstract

The invention discloses a method and a device for determining the position of a potential fracture surface of a two-stage reinforced soil structure. The method comprises the following steps: carryingout model design of actual engineering of a two-stage reinforced soil structure through similarity comparison to obtain a test model; performing a reinforced soil structure anti-seismic test on the test model on a vibration table to obtain test data; analyzing and processing the test data, and determining the maximum strain point position of the test model; and deriving and determining the position of a potential fracture surface based on the maximum strain point position. According to the method and the device for determining the position of a potential fracture surface of a two-stage reinforced soil structure, the position of a potential fracture surface of a two-stage reinforced soil structure can be determined, the blank of insufficient research on the position of the potential fracture surface of a two-stage reinforced soil retaining wall at present is filled, the influence of earthquake action is considered in the process, and the method and the device have better applicability.

Description

technical field

[0001] The invention relates to the field of construction safety, and more specifically relates to a method and a device for determining the position of a potential rupture surface of a double-stage reinforced soil structure. Background technique

[0002] Reinforced earth retaining wall has been widely used in construction field because of its simple structure and fast construction speed. With the continuous improvement of construction demand standards, the application of double-stage and multi-stage reinforced soil is becoming more and more common.

[0003] The determination of the potential fracture surface is the key to the length design of reinforced soil structures, such as figure 1 , is a schematic diagram of the fractured surface of a reinforced soil structure. The interior of the reinforced body is divided into active area and anchorage area according to the stress of the reinforcement: the active area is the area on the left side of the rupture sur...
