道路窨井差异沉降计算分析

在道路中,窨井沉降导致了路面与窨井之间的差异沉降,出现道路平整度问题,影响行车舒适性与安全性。该文针对当前道路窨井沉降问题,提出了防治窨井沉降的改进型窨井结构,并结合路基处治,进行了详细的计算分析,结果表明该结构能较好地减小窨井与路面差异沉降大小,推荐采用改进窨井并进行路基浅层加固,可以较好地防治道路窨井沉降问题。

Analysis on Calculation of Difference Settlement for Road Manhole

In the roads,the manhole settlement will results in the difference settlement between the pavement and manhole and the levelness problem of road to affect the driving comfortableness and security.Aiming at the present settlement of road manhole,the article puts forward the improved manhole structure to prevent the manhole from the settlement,and carries out the detail calculation and analysis with the roadbed treatment.The result shows that this structure can better decrease the difference settlement between the manhole and the pavement.The improved manhole is recommended able to better prevent the road manhole from the settlement.
