长江口细砂作为路基填料的设计方法

崇明岛地处长江口,地势平坦填筑高速公路路基所需的土源匮乏,长江口地区细砂来源丰富,若能结合航道疏浚产生的细砂作为路基填料则为生态岛的建设创造了有利条件。该文阐述了长江口细砂特定的物理力学特性,并且针对其区别于其他路基填料的特性提出设计要点,为土方匮乏区域路基填料的选择提供了新的方向。

Design Method of Fine Sand in Changjang River Estuary Roadbed Stuffing

Chongming Island is located at the estuary of Changjiang River,and its topography is flat, where goes short of soil source required for constructing the roadbed of expressway.The source of fine sand at the estuary of Changjiang River is abundant.If the fine sand produced from dredging up of the sea route is taken as the roadbed stuffing,the advantage condition is created for the construction of ecological island.The article sets forth the specially physical mechanics characteristic of the fine sand at the e...
