Measurement method of landslide or rock mass deformation during construction excavation

Abstract

The invention discloses a method for measuring landslide or rock mass deformation during construction excavation, and relates to the field of geological disaster investigation, design and prevention of slope engineering. It includes the following steps: Step 1: drill the first hole at the rock mass at the upper part of the landslide body or the outwardly inclined structural surface, and drill the second hole at the rock mass at the lower part of the sliding bed or the outwardly inclined structural surface; Step 2: Insert the stylus into the second hole in one hole; insert the scale into the second hole; step 3: the landslide or the topographic slope of the slope at the shear exit of the rock mass deformation is a, the inclination angle of the sliding belt or the outwardly inclined structural surface is b, and the measuring needle and the sliding h 1 , the height between the stylus and the scale is h 2 ; Step 4: Record the horizontal displacement of the pointer on the dial every day, and make a time-horizontal displacement curve. The invention realizes that the equipment is convenient to manufacture, relatively simple to install, and the method is feasible and practical.

Description

technical field [0001] The invention relates to the field of geological disaster investigation, design and prevention of slope engineering in industries such as water conservancy and hydropower, municipal administration, transportation, electric power, etc., more specifically, it is a method for measuring landslide or rock mass deformation during construction and excavation. Background technique [0002] During the construction and excavation of slope engineering in water conservancy and hydropower, municipal, transportation, electric power and other industries, geological conditions such as cutting feet at the front edge of landslides and unfavorable structural surface combination blocks of rock slopes are often encountered. At this time, it is necessary to timely Grasp the deformation trend of geological structure types such as landslide mass or rock mass at the top of the outwardly inclined structural surface after cutting the foot, and the unfavorable structural surface c...

Problems solved by technology

[0003] At present, deformation monitoring is generally used for landslides or rock mass deformation at home and abroad. Deformation monitoring has the characteristics of periodic repeated measurement, high precision, comprehensive application of various measurement technologies, and the monitoring network focuses on the study of potential changes. However, deformation monitoring also has the characteristics of early stage Disadvantages such as long layout time, inconvenient layout, and relatively high cost
