- Abstract
In order to further simplify the planning and design program of saline land subsurface drainage system in the Yellow River delta, the real situation in the project area combining with typical examples of land construction project was analyzed and the theoretical model which was based on the key parameters of subsurface drainage project and simplified solution method were discussed. The results show that the use of single-stage subsurface pipe is suitable for the Yellow River delta. The material of subsurface pipe used in the study is PE double partition wave veins plastic drilled pipe and the pipe diameter is 110mm. The buried depth of underground pipe is suggested to be 1.2-1.7m. Various salt-discharging standards are used to calculate the drainage modulus. By the combination of drainage modulus and hydraulic conductivity of regional drainage soil, we provided a subsurface drain spacing chose reference data. According to the reference data, we found the design spacing length of subsurface pipe in the study region should be 17-27 m and the average length was 22 m.
