摘　　要：本文研究了引滦入港工程水下穿越管道土质情况,对土层的主要物理、力学性质进行实验分析,并设计了实验室装置,进行5种工况实验分析,得出了有益的结论。Quality of soil around the underwater penetrating pipeline which was used to draw Luanhe river to the port was studied in this paper. Based on the experimental analysis of main physical and mechanical properties of soil stratum, experimental installation was designed and five kinds of operating mode were analyzed accordingly. Some conclusions are drawn.
