Analysis and reinforcement design case of deep silt excavation accident

Through the analysis and reinforcement design case of a deep silt excavation accident, it is indicated that the selection of excavation structures is very important. With regard to the distinct thixotropic and rheological characteristics and poor engineering mechanical properties of the marine sedimentary silt, the safety reliability and practicability of the excavation structures should be assessed. The possible danger should be predicted. The relevant plan and design measures should be formulated.
