Abstract

The invention discloses a monitoring and verification system and method for an overall failure mode of a soil and rock double-element side slope. The method comprises the steps that (1) the side slopeis simulated through finite element software, and the slip line of the side slope is obtained; (2) the monitoring scheme for monitoring displacement changes on the slope top and the potential slip face is made according to the side slope construction scheme; (3) construction is carried out according to the laying scheme, and monitoring is carried out; (4) monitoring data are collated, the disablement change condition of the surface and the interior of the side slope is analyzed, and especially displacement changes on the interface of soil and full decayed rock and the interface of full decayed rock and strong decayed rock are analyzed; (5) the displacement change condition of the surface of the side slope is obtained according to monitoring and analysis, the position of the slip line is confirmed, and the slip line of the side slope is drawn according to the maximum displacement point in the side slope; and (6) according to the obtained side slope slip line, the slip line obtained through the finite element method is verified, and guidance is provided for next side slope support structure construction through the finite element software.

Description

technical field [0001] The invention relates to the field of slope failure mode monitoring, in particular to a monitoring and verification system and method for the overall failure mode of soil-rock dual-element slopes. Background technique [0002] In the process of foundation pit excavation and road construction, sometimes a slope with soil layer on the upper side and rock on the lower side is encountered, which is called soil-rock dual element slope. At present, the theoretical circle generally believes that the failure mode of the soil slope is an overall circular arc; the overall failure mode of the rock slope is more complex, related to the rock properties, and presents diversity. There is a lack of research and consensus on the overall failure mode of soil-rock dual-element slopes at home and abroad. [0003] In recent years, with the continuous development of Jinan's urban construction, four types of soil-rock dual-element foundation pit slopes have emerged. Accord...
