Embodiment Construction

[0019] This embodiment describes in detail the risk assessment method of the present invention for a waste slag site in a certain place.

[0020] For a spoil site in a certain place, it is necessary to conduct a risk assessment. First, it needs to be divided into regions to determine the survey area of ​​the spoil site.

[0021] S1: According to the original topographic map and design map of the location of the spoil site, combined with the electronic image map, determine the survey area of ​​the spoil site. The area should include the spoil site body and the upstream to the watershed of the spoil site, and within 300 meters downstream sensitive source, and the mapping accuracy should be better than 1:2000. Among them, sensitive sources include important infrastructure, public facilities, industrial enterprises and residential areas.

[0022] After obtaining the survey area of ​​the spoil yard, start to measure and investigate the survey area of ​​the spoil yard.

[0023] S2...

Abstract

The invention relates to the technical field of engineering geological hazard assessment, in particular to a multi-index system assessment method for hazard of slag dump. The method comprises the following steps of: 1) determining an investigation area of a slag dump; 2) carrying out geological survey on that dregs disposal site; 3) quantifying that slope conditions and the topography and geomorphology condition of the dregs dump site, and determining the properties of the dregs dump material and the geological condition indexes of the dregs dump site; 4) establishing a hazard evaluation modelincluding that slope condition of the slag dump, the properties of the slag dump materials, the meteorological condition of the slag dump site, the topographic and geomorphological condition of the slag dump site and the geological condition of the slag dump site, obtaining the hazard parameters of the slag dump site by weighted summation, and determining the hazard level of the slag dump site. The invention fully considers various parameters affecting the hazard of the slag dumping site, quantifies the parameters, obtains the hazard parameters of the slag dumping site by a weighted summationmode, classifies the hazard parameters according to the hazard parameters, and is convenient for engineers to grasp the hazard parameters quickly.

Description

technical field [0001] The invention relates to the technical field of engineering geological risk evaluation, in particular to a multi-index system evaluation method for the risk of spoil yards. Background technique [0002] With the occurrence of major landslide accidents at the muck receiving site in Guangming New District, Shenzhen, the state and relevant competent authorities have paid more and more attention to soil and water conservation, especially the stability of the spoil site. The status and conclusions of the stability assessment of the spoil site It is a prerequisite for the acceptance of water and soil conservation facilities. [0003] At present, there is no specific stability assessment specification for spoil dumps. The stability analysis of spoil dumps is mainly based on the measured topographic maps and survey data, and selects typical sections for stability calculation and analysis, which requires professionals to complete, and the timeliness is poor.
