非开挖铺设地下管线对公路沉降的影响

Influence of Non-excavated Laid Underground Pipeline on Highway Settlement

利用非开挖铺管技术进行穿越公路的工程建设,会对公路下地层产生扰动,该扰动会使公路产生一定沉降。该文分析了非开挖施工引起地层扰动的因素,介绍了Bennet(t1998)创建的地表沉降预测计算方法,并结合工程实例,对公式进行了运用,提出了非开挖铺管技术减少对公路沉降的措施。

The use of non-excavation laying pipe technology in the engineering construction crossing highway will produce the disturbance on the stratum underneath the highway.This disturbance will make the highway produce some settlement.The article analyzes the factors of the stratum disturbance caused by the non-excavation construction,introduces the ground settlement forecast calculation method established by Bennett in 1998,and puts forward the measures of non-excavation laying pipe technology to decrease the highway settlement by the engineering cases and the use of formula.
