摘要
进行了泊江海孜矿白垩系、侏罗系地层的冻结岩土物理力学性能试验,并与两淮地区冻结岩土数据及相关材料试验数据进行横向比较,得出了泊江海孜矿白垩系、侏罗系地层的冻结岩土工程参数特性。对今后在白垩系、侏罗系地层冻结法凿井的设计及施工有着较为重要的参考价值。
The experiment study on physical and mechanical properties of frozen rock in Cre- taceous and Jurassic stratum in Bojianghaizi Mine was carried out, then the horizontal comparison between this experiment rerults and the experimental data of frozen rock-soil data and other rela- tive materials in Huainan and Huaibei Cities was conducted, which achieved the parameter char- acteristics of frozen rock-soil engineering in Cretaceous and Jurassic stratum in Bojianghaizi Mine. This study had quite important reference values for the design and construction of freezing shaft sinking in Cretaceous and Jurassic stratum in future.
