摘要
由于软土地区的高压缩性,该区域的道路下排水管道受各种因素的影响,出现纵向垂直变位。在接口顶部,由于承受不了拉应力而开裂。排水管内水会渗入地层污染地下水,同时地下水也会带着土粒从裂缝中流入排水管内,并且引发路面坍塌或地下水污染等危害。该文对这些病害结合工程实例情况,提出了治理措施,可供类似工程参考。
The drainage pipes under the roads of the soft soil area are affected by various factors because of high compressibility to cause the longitudinal vertical displacement.The top of inlet is cracked because of not bearing the tensile stress.The water in the drainage pipe can seep into the stratum to pollute the underwater,and at the same time,the underwater also bring the soil grain to flow into the drainage pipes from the cracks and will cause the harm of pavement collapse or underwater pollution.The article puts forward the treatment measures for these diseases according to the engineering practices,which can be referred for the similar projects.
