subdrainage

1. Simulation of Soil Moisture Fluctuation in Winter Wheat Fields under Subdrainage and Seepage Irrigation

地下排水和渗灌条件下麦田土壤水分变化模拟

2. subdrainage structure

地下排水构筑物

3. The pavement subdrainage system removes excessive subsurface water to the edge of highway in time, so it can improve pavement performance and extend service life.

如果在路面内部设置排水系统，将路面结构中的内部滞水及时排除到路面和路基结构外，可以改善路面的使用性能，提高其使用寿命。

4. The karst depression belongs to the accumulative area of surface water and subdrainage area of subsurface water, the karstification is relatively week, and reservoirs are undeveloped.

岩溶斜坡和岩溶洼地为地表水汇集区及地下水排泄区，岩溶作用相对较弱，储层不发育。

5. lean cement subdrainage base

贫混凝土透水基层

6. Discharge Ability of Lean Cement Subdrainage Base

贫混凝土透水基层的排水能力

7. This method can acurately simulate the flow direction in gird near river,and can keep the direction of waterflow from crossing the watershed of subdrainage area.

这样既可以较精确地反映出河道附近格网的水流方向,又可以让各个子流域内的汇流方向和水流方向不会跨越子流域的分水岭。
