drainage pipe slope的意思|示意

The physical model tests were performed to study the influence of pipe drainage system on soil permeability, groundwater level and slope residual downslide thrust.

为了研究管网渗流系统对土体渗透性能和地下水位以及边坡剩余下滑推力的影响，进行管网渗流系统的物理模拟试验。

Pipe drainage of groundwater are often developed in the pebbly clay slopes and are important in restricting groundwater level rising and in keeping slope stability.

含碎块石土质边坡中常发育有地下水排泄管道，他们控制地下水水位上升，对保持边坡稳定十分重要。
