摘要
上海海岸带位于长江三角洲的前缘。由于长江每年携带大量泥沙,在潮汐动水力作用下,使海岸不断向外伸涨成滩涂。随着上海土地资源的紧缺,开发与利用滩涂,成为上海的当务之急。目前在卢潮港等地正在对滩涂兴起大规模的促淤圈围,而圈围前期的岩土工程勘察尤其重要。对圈围场地的工程地质条件,对围堤的稳定及沉降;对吹填沙源均需进行分析评价。该文对南汇东滩圈围场地的岩土工程地质勘察进行了总结。
The coastline of Shanghai is in front of the delta of Yangtze River. Under the effect of tide, the silt brought by Yangtze River continuously formed the tidal fiat outwards. With the lack of soil, it is urgent to develop and make use of the tidal flat. Currently, a large amount of tidal flat is formed in Luchao harbor, etc, and geotechnical investigation of earlier stage is very important. The engineering geology condition, the stabilization and settlement of bank and hydraulic fill must be analysed and evaluated. The geotechnical geological investigation of Dongtan in Nanhui District was generalized.
