Analysis of the cause and evolutionary law of rock-soluble ground collapse
In order to systematically clarify the cause and evolution mechanism of the collapse of the rock-soluble ground,to review the literature,to understand the research status and development trends of the collapse of the rock-dissolved ground through detail;summarize the research results of the cause and mechanism of the rock-soluble ground collapse in recent years,and organize it.And analysis,studies have found that there are three necessary basic conditions for the collapse of the rock-soluble ground.First,there must be developing rocky soluble.There are soluble rocks,especially carbonate rocks.Under the influence of flowing water containing CO2,it is deposited to produce a hole to form a developed rock-soluble.The more prone to collapse of the loose soil layer,the less likely to occur;Third,the most important thing is the groundwater power conditions.On the basis of the above two conditions,the rich underground water flow activity is also required to etch and erosion of the stratigraphic structure.The cause and evolutionary mechanism of rock-soluble ground collapse are different due to different causes and different geological structure conditions.The study can provide theoretical basis and technical support for engineering construction and geological disaster prevention and control.
