摘要
进行了下第三系红层低温下物理力学性能试验,并将试验结果与第四系表土地层试验结果进行比较。通过对红层控制层位的冻结壁外荷载、厚度、平均温度的计算,同时根据两淮地区成功井筒冻结的设计和施工经验,提出深厚红层冻结设计方案与一些合理建议。
The physical and mechanical properties tests of the paleogene red beds were carried out under low temperature,and the test results were compared with the table land layer of Quaternary.Through the calculation of the external load,the thickness,the average temperature of the frozen wall in the red beds control layer,and based on the successful design and construction experience of the frozen shaft in Huai River regions,the freezing design program of the deep red beds are proposed and some reasonable proposals are put forwarded.
