土工合成材料在潮汐河口地区水库建设中的应用

介绍了土工合成材料在潮汐河口地区的上海陈行水库和青草沙水库等工程建设中的应用情况。通过对土工管袋、软体排、网兜石等土工合成材料的保砂性、透水性、防堵性、抗冲性以及深水堤软土地基的塑料排水板排水固结处理等进行计算分析、试验研究和工程实践,提出了土工合成材料用作水库堤坝各区域反滤、排水、防冲体的选用原则和通常选用的规格,以期为潮汐河口地区水库建设提供借鉴。

Application of geosynthetics to reservoir construction in tidal estuary area

The application of geosynthetics to the Chenhang reservoirs and Qingcaosha reservoirs in a tidal estuary area is described.The sand-retaining ability,permeability,anti-blocking ability,and anti-scouring ability of pipe-shaped sacks,soft mattresses,and stone baskets,and the drainage consolidation of the plastic drainage plate in a soft foundation were analyzed through calculation analysis,experimental study and engineering practice.The principles and specifications of selecting geosynthetics for filtering,drainage and anti-scouring bodies are put forward,providing some reference for reservoir construction in tidal estuary areas.
