Dredging is an effective method to control endogenous pollution of water, but the disposal of dredging sediment has become a new environmental problem. The research shows that resource utilization is the fundamental way to solve this problem. Taking a pilot project of internal pollution control as an example, this paper introduces the different directions of resource utilization of dredding sediment without heavy metal pollution, such as pong ecological restoration, green planting soil, water storage clay, hollow mortise and tenon structure block, and the operability, economy and other aspects of each utilization mode were comprehensively compared and summarized. It provides a reference experience for the disposal of other dredging sediment.
The inverted siphon of Huaihe River（Ⅰ） is surveyed according to the survey accuracy in the preliminary design stage.According to the survey data, the hydrogeological and engineering geological conditions and existing engineering geological problems in the building area are carefully analyzed, summarized and evaluated, which provides reliable physical and mechanical parameters of rock and soil mass and foundation treatment measures for designers.
