Problems solved by technology

[0006] In view of the above analysis, the present invention aims to provide a control method for karst ground subsidence based on a cloud model, to solve the problem that the existing control methods do not consider the impact of ambiguity and randomness on the evaluation of karst ground subsidence grades. There is a large deviation between the grade evaluation results and the actual situation, and it is difficult to scientifically guide the prevention and control of karst ground subsidence

Embodiment 2

[0075] This embodiment uses a specific case of karst ground collapse in Tangshan City to further illustrate the first embodiment:

[0076] The cloud model-based treatment method for karst ground collapse in this embodiment includes the following steps:

[0077] Step 1: Determine the factors affecting karst ground collapse. According to the analysis of the disaster mechanism of the karst ground collapse of the Tangshan Stadium, the influencing factors of the karst collapse can be attributed to two main factors: water and passage. Specifically, the up and down fluctuations of water near the soil-rock interface are the external dynamic conditions of karst collapse. The caves and crevices formed by the dissolution of soluble rock, and the breakage of the bedrock makes the caves and crevices easy to connect to form the drainage channels and the first The water resistance of the bottom water barrier of the Quaternary system decreases or even fails, which leads to the formation of skylig...

Abstract

The invention relates to a karst surface collapse treatment method based on a cloud model, belongs to the technical field of geological disaster evaluation and prevention and control, and solves the problem that an existing method is difficult to scientifically guide karst surface collapse prevention and control. The treatment method comprises the following steps: determining karst surface collapse influence factors; collecting and screening related engineering instances, and performing classification and grading; and calculating the cloud model digital characteristics of each influence factor, the weight of each influence factor and the determinacy of each risk level under the condition of different levels of karst surface collapse risk, obtaining a comprehensive determinacy, obtaining the karst surface collapse risk level of the to-be-evaluated site according to the maximum value of the comprehensive determinacy, and making a treatment scheme. According to the method, a cloud model theory is applied to convert a karst ground risk level concept with fuzziness and randomness characteristics into quantitative determinacy. A brand-new karst ground collapse risk level evaluation and treatment system is established, and a scientific basis is provided for prevention and treatment of karst ground collapse.

Description

Technical field [0001] The invention relates to the technical field of evaluation and prevention of geological disasters, in particular to a method for treating karst ground collapse based on a cloud model. Background technique [0002] Karst collapse is one of the six major types of geological disasters in my country. It is a unique geological disaster in karst areas. It is mainly distributed in densely populated karst areas in southwest my country, southern China, and China. Since karst ground collapse is sudden in time, concealed in space, and once it occurs, it will have serious follow-up effects. Therefore, the risk assessment of karst ground collapse is the focus of the technical field of karst ground collapse disaster prevention and control. one. [0003] The existing methods for evaluating the risk of karst ground collapse include qualitative evaluation, theoretical formulas, numerical calculations and statistical mathematical methods. Among them, the qualitative evaluati...
