The State of the Art and Prospects of Excavations Engineering

The excavations engineering, which is a traditional topic, has an epoch-marking characteristics in geotechnical engineering. With the process of urbanization, the excavations engineering is confronted with new problems. Firstly, the retaining and protection structure (RPS) which is common at present is introduced. Then, their applicable conditions and advantages and disadvantages are discussed, which can provide basis for selecting the RPS in excavations engineering. On this basis, some important problems which exist in the supporting technology are analyzed, and the developing trend is prospected for the supporting technology in excavations engineering.
