Abstract: As a huge metropolis, the highly intensive development and utilization of underground space in Shanghai has become the distinct trend of urban construction. Combined research among more than 100 industrial and civil construction projects in the city finds that soil erosion during the construction of underground works accounts for a significant proportion (50%~60%) of the totality of soil erosion or degradation. In order to further promote the precise management and control of water and soil conservation in the procedure of construction engineering projects, this paper analyzes the relationship between foundation pit supporting measures and water and soil conservation results in typical underground engineering examples. Through summing up the high frequency risk points of water and soil loss caused by underground engineering of housing construction projects in Shanghai, several positive methods for preventing and controlling water and soil erosion could be contributed correspondingly for the future work, such as pretreatment of the drilling caving of bored piles, and making full use of the soil produced by underground excavation.

Key words: underground engineering; risk analysis; water and soil conservation measures
