| Abstract: | Abstract： Deep excavations tend to be complex systems engineering under complex hydrological/geologi- cal conditions as well as rigor construction requirements such as working face, environment protection, etc. This paper illustrated the application of locking steel pipe pile cofferdam and section steel struts in re- taining and protection for Na-ehao River bridge deep excavations. It showed that this scheme is stable, re- liable, and has good water-locking function and recoverability as well. |
