建立珠江三角洲一维河网潮流数学模型和工程附近二维潮流泥沙数学模型，分析了工程河段洪枯季水流运动特性，合理设计了极限冲刷计算的水文、泥沙、底质参数和相关条件，对陈村水道可能发生的极限冲刷进行了研究预测，根据计算结果对极限冲刷前后隧址附近河床断面、剖面、滩槽格局等形态变化进行了分析，对隧道埋深的合理性进行了评价。
建立珠江三角洲一維河網潮流數學模型和工程附近二維潮流泥沙數學模型，分析瞭工程河段洪枯季水流運動特性，閤理設計瞭極限遲刷計算的水文、泥沙、底質參數和相關條件，對陳村水道可能髮生的極限遲刷進行瞭研究預測，根據計算結果對極限遲刷前後隧阯附近河床斷麵、剖麵、灘槽格跼等形態變化進行瞭分析，對隧道埋深的閤理性進行瞭評價。

1D stream model is made for the Pearl River delta networks and 2D stream-sediment model for engineering neighboring river.Engineering river current stream characteristic during flood and dry season has been analyzed , the conditions of limit scour , such as hydrology , sediment, sediment parameters and the other conditions , have been rationally designed .Besides, limit erosion that might happen in Chencun river has been forecasted .Based on the result , morphological changes of riverbed cross section , beach and slot situation after limit scour have been studied , and the rationality of burying deep for the tunnel has been estimated .
