土工复合排水网渠道排水的应用

水对土体的浸湿、饱和作用，将引起土体强度的降低，将引发各种工程病害。渠道地基土体强度不足，承载力降低，将会引起起到防渗结构的破坏；边坡土体强度不足，可能引起边坡变形甚至失稳；水是地质病害产生的主要原因。因此，做好基础的防排水工作，使得地下水不侵扰防渗结构，是保证防渗结构稳定和有效的关键。

The Application of Geotextile Composite Drainage Webs in the Channel Drainage

The soak and saturation of water to soil mass can decrease soil strength and bring hazard in engineering. The decrease of soil strength and bearing capacity in channel base will cause the broken of anti-seepage structure and that in slope will make the slope deformation and unstablization. Water is the main cause of the geological hazard in channel. The water proof and drainage is the key point in order to ensure the stablization and normal function of anti-seepage structure and avoid to disturbe the base structure by groundwater.
