为解决塔克拉玛干沙漠石油井场干粉砂场地基础施工过程中遇到的浸砂坑浸水量计算问题．根据浸水坑蓄水高度为零，砂是各向同性的均质体和水在粉砂中的流动呈层流状态等假设，引用达西渗透定律，对干粉砂场地上的浸砂坑浸水量问题进行了理论分析．通过理论分析，得到了塔克拉玛干沙漠井场干粉砂场地基础施工中常见的圆形、矩形和“Π”形浸水坑的浸湿砂体积计算公式；引入了持水量的概念，给出了上述三种浸水坑的浸水量计算公式．上述公式的建立，可以使塔克拉玛干沙漠井场中的浸水坑施工由经验判断走上理性设计的道路，并由此节约大量的抽水、运水费用．
To solve the Taklamakan desert oil well field dry silt foundation construction encountered in the process of immersion sand pit immersion problem. According to the assumption that the height of impoundment water is zero, the isotropic homogeneous body of sand and the laminar flow of water in silt are laminar flow conditions, Darcy’s law of permeability is introduced. The problem is analyzed theoretically. Through the theoretical analysis, we get the formula of the volume of soaked sand commonly found in the dry sand silt field in the Taklimakan Desert wellsite. The formula of the volume of soaked sand is introduced. The concept of water holding capacity Baptist water immersion volume calculation formula. The above formula can make the construction of the immersion pits in the wellsite of Taklamakan Desert take the path of rational design by experience and save a lot of pumping and transporting costs.
