柔性管应用到上埋式过水涵管会遇到很多问题, 对症下药才能使其应用成为可能。从柔性管工作机理入手, 提出了/ 开槽法0的施工措施。首先对施工措施的理论根据进行解读, 然后通过对HDPE 缠绕增强管按此工艺进行 现场试验来检验该措施的可行性。从滑线电阻位移传感器测得的变形值及光纤光栅测得的应变数据表明, 采用/ 开 槽法0 施工后, 管变形及应变量均极小, 无弹性失稳现象, 从而证明采用/ 开槽法0 进行施工充分发挥了周围土体的作 用, 可将柔性管成功地用于上埋式过水涵洞。

Applicatio n of the flex ible pipe to the buried embankment culver t encounters many pr oblems, and determination of the appro pr iate metho d can make it wo rk. In this paper, t he wo rking mechanism of flex ible pipe was int roduced, and the constr uctio n measure o f "Groo ving metho d" was pro po sed. T he r atio nale of the const ruct ion measur e was ex plained, and then the feasibility of the measur e was ver ified throug h the field tests for H DPE w inding reinfor cement pipe. Based on the deformatio n v alues measured by the slide r esistance displacement sensor and the strain dat a measured by the fiber g rating , the defo rmatio n and st rain of t he pipe are minimal and the pipe has no elastic instability after t he construction w ith / Gr oo ving method0, w hich indi2 cated that / Groo ving met ho d0 can develo p the ability of sur ro unding soil and ther efo re the flex ible pipe can be used for bur ied discharg e culvert using this metho d.
