【摘要】 近20多年来,我国地层人工冻结工程技术取得了重要进展,深井冻结基本杜绝了大规模断管事故的发生,冻结法施工已成功推广应用到地铁等复杂的市政工程。本文最后指出了目前应用中尚存在的问题,今后在冲积层大于500m情况下冻结法凿井及其他工程应用要进一步解决的问题。更多还原

【Abstract】 Twenty years newly, manpower’ s frozen soil engineering technology of our country’ s stratum made great progress. Frozen soil engineering technology of deep well eliminated many accidents of broken pipe. Frozen soil engineering technology was applied in complex civil project, for example, underground. This text pointed out using problem at present and for the future should solve problem of more than 500m rushing stratum and other engineering appliance.更多还原
