The following conclusions were drawn from the study: (1) Silt in the Estuary originated mainly from river load and tidalload.
结果表明：（1）泥沙主要来源于河流输沙和潮流输沙；
2
The monitoring results must be adjusted according to tidal changes in-order to study the relativity of axial force of piles and load of upside structure.
为了建立基桩轴力与上部结构荷载的相关性，必须对观测结果进行潮位影响的修正。
3
Based on the study of sediment transport under the actions of tidal currents and wind waves a mathematical model of suspended load and bed load for Yangtze estuary is developed.
