湿陷性黄土地区道路地下空洞病害发育的几何物理属性研究
摘要
Abstract
With the increasing attention uponurban road collapse accidents,the market for detecting underground disease bodies on urban roads is also increasing year by year.However,the current exploration stage mainly focuses on the detection of underground disease bodies on urban roads,pattern recognition,and analysis of disease causes,without analyzing and studying the inherent attributes of underground disease bodies on roads.Based on this,this study conducted a physical parameter study on the development of voids beneath cement concrete pavement in collapsible loess areas based on the results of 3D geological radar detection and drilling verification data.Furthermore,for the first time,an innovative approach was proposed based on the geometric development and spatial characteristics reflected by the parameters of the top depth,bottom depth,plane area,and volume of the cavity,proposing the attributes of underground disease bodies.The geometric and physical properties of the identified cavity disease bodies were also studied.Research has shown that when analyzing a cavity disease body from a single top depth attribute,bottom depth attribute,clearance attribute(net depth attribute),plane area attribute,and spatial volume attribute,the single physical parameter interval of the cavity can be basically grasped,and then the development of the cavity in a certain road can be obtained;The study of multi-attribute correlation analysis can evaluate the single attribute interval and risk of road cavity development,and then evaluate the risk of collapse and losses caused in the early stage,providing scientific,rapid,and accurate geophysical basis for government departments to deal with cavity diseases.The research methods and achievements of this study provide new research ideas and methods for the detection industry of underground disease bodies on urban roads,and have a certain guiding role for road collapse warning.关键词
