深厚钙质粘土地层冻结压力的实测与研究

Actual test and research of deep and thick calcium sticky layer freezing pressure

结合工程概况,介绍了深厚粘土层及混凝土井壁进行动态监测的测试方案,并对井帮温度和冻胀力对冻结压力的影响及冻结压力随深度的变化规律进行了分析,以保证井筒掘砌的安全、快速施工。

Combined with general condition of project, it introduces the testing plans of moving supervision of deep and thick sticky layer and concrete wall, analyzes well temperature and freezing expanded force＇s effect to freezing presure and its changing law with depth, in order to ensure the safety and fast construction of well digging.
