Abstract

The invention particularly relates to a monitoring method and system for an adjacent rock stratum above a side slope weak intercalated layer, and belongs to the field of side slopes, and the monitoring method comprises the steps that the water content of rock-soil bodies of a plurality of test points of the adjacent rock stratum above the side slope weak intercalated layer is obtained; obtaining the void ratio of the rock-soil body of the plurality of test points; according to the water content and the void ratio of the rock-soil body of each test point, the saturation of the rock-soil body of the corresponding test point is obtained; monitoring the rock stratum according to the saturation degree of the rock-soil body of each test point; wherein the test points are at least distributed at the top, the middle and the bottom of the rock stratum. According to the method, representative test points arranged at the top, the middle and the bottom of the adjacent rock stratum above the soft interlayer of the side slope are obtained, the water content and the void ratio are obtained, the saturation degree of a rock-soil body is calculated, and therefore the adjacent rock stratum above the soft interlayer of the side slope is monitored.

Description

technical field [0001] The present application relates to the field of slopes, in particular to a method and system for monitoring adjacent rock formations above weak interlayers of slopes. Background technique [0002] The weak interlayer is a thin layer of mud shale containing carbonaceous and other mineral components. Compared with the upper and lower rock layers in the slope, there are large differences in lithological structure and structure, resulting in significantly different engineering geological properties from the upper and lower rock layers. , which is mainly characterized by low mechanical strength and poor water stability, and is the "weak link" in the slope. Heavy rainfall is one of the main causes of slope instability and failure. Rainfall infiltration can easily cause a transient saturation zone in the rock and soil on the upper surface of the weak interlayer in the slope, which affects the mechanical parameters of the weak interlayer and leads to the weakn...
