The harbor at Chungking, a major commercial and industrial center on the Yangtze River, is afflicted by serious silting. 重庆是长江岸上的大商埠和工业中心，港内泥沙淤积严重。
It is demonstrated that evident siltation is created within the dike body at the collapsing pit with better silting effect after the examinations made in several flood seasons. 经过几个汛期的检验，坝体内崩窝处淤积明显，沉梢坝起到了显著的促淤效果。
