摘要
冻结壁交圈前的发展速度是冻结设计中的重要参数,而关于白垩系地层冻结速度的研究却很少。通过地层热物理特点分析和测温孔数据分析,对大海则地区白垩系地层进行了研究,得出类似地层在冻结方案设计时可以考虑冻结速度为30 mm/d左右,为今后类似地层冻结设计提供参考依据。
The speed of freezing before ice wall form is the important parameters in freezing design,but few study about it in the cretaceous strata could be found. By analyzing the thermal physical parameters and data of the temperature measuring hole,researched the characteristic of the cretaceous strata and concluded that the speed of freezing was about 30 mm / d in freezing design which to provide reference for future similar ground.
