某铁路专用线盐渍土路基地基处理措施探讨

Discussion on a special railway line Saline Soil Foundation Treatment Measures

盐渍土地区路基地基处理和路基病害防治措施是铁路设计、施工、运营各行业共同关注的重点问题。论文依托新疆地区某铁路专用线工程,对工程所在地区的盐渍土特性:盐胀性、溶陷性、湿陷性和毛细水作用进行了分析,并结合现场勘察和室内试验,认为工程所在区域受盐胀性、溶陷性和毛细水作用影响较强。最后结合盐渍土地区常见工程处理措施,提出工程所在区域的地基处理原则和措施,并对处理措施进行对比分析,提出工程所在区不同段落的地基处理措施。

Foundation treatment measures and disease prevention of railway in saline soil area are key issues of railway design, construction and operation of the various sectors of mutual interest. Relying on a special paper in Xinjiang railway line project, saline soil characteristics of the region where the project ： Expansion of salt, dissolved collapsible and capillary action of water were analyzed, and combined with field investigation and laboratory tests, that the project is located expansion of the area affected by salt, dissolved collapsible and capillary action of water strong influence. Finally, the saline soil area common engineering treatment measures proposed project area where the foundation principles and measures and treatment measures were analyzed, foundation treatment measures put forward different sections of the district project.
