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.

参数和地震激励的随机性对土-结构动力相互作用的影响，土与结构动力学参数的不确定性和地震激励的随机性是众所周知的，其对结构响应的影响也是很重要的，对于结构的地震响应有重要影响的土-结构动力相互作用考虑各种随机因素的影响也是必然的发展趋势。

Result After the ground-source heat pump system ran continuously for a period of time, the temperature field in the range with the semidiameter of 0.8 m around the underground pipeline showed intensive changes. The changes of the temperature field in the area outside this region became smaller till it was close to the original temperature of soil. The original temperature field in the soil of shallow ground surface showed an exponential correlation with the depth. When the depth reached to certain extent, the soil basically maintained the constant-temperature state and it was 1~2 ℃ higher than the annual average temperature.
