查询词典 vacuum tube

The research work done is presented as follows:Compound dewatering technique of vacuum tube well is an effective technology for solving the dewatering problems of aquitard and interface relict water according to physical simulation test and field test. The variation laws, such as degree of vacuum, pore water pressure in different strata, have been studied. The results show that there is a certain scope of influence of vacuum in strata, and the vacuum degree in the horizontal direction decreases gradually with the increase of the distance from the main well; the change law of degree of vacuum in the vertical direction increases firstly and then decreases with the depth of soil strata, and changes with different soil nature and depth; changes of pore water pressure in soil strata has also shown a similar law of degree of vacuum.

主要研究工作如下：通过室内物理模拟试验和现场试验均证明了真空管井复合降水技术用于解决弱透水层和界面残留水疏干难题的有效性；并且对不同地层中真空度、孔隙水压力等变化规律进行了研究，发现地层中真空度均有一定的影响范围，且真空度在水平方向上随距主井距离的增加而逐渐降低；在垂直方向上真空度随深度总的规律是先增加后降低，并随土层性质及深度的不同而变化；土层内孔隙水压力也呈现出与真空度类似的变化规律。
