1.工程情况息县至光山高速公路是国家规划的大庆至广州高速公路的重要组成部分。№.5标段位于河南省信阳市光山县境内,起讫桩号K51+000～K59+000,地质以第四系中更新统低液限粘土为主。我标段所承建的路段,多穿越水稻田,浅层土质湿软,工程性质差,大多路段不能直接进行碾压。根据我标段离周围砂场较近、砂源丰富的优势,对湿软的原地基做换填中粗砂处理。土质较好,承载力交高的非湿软地基,清表后,可直接进行填前碾压。通过试验段的成功试验,以及后来施工中
1. Project Information The Xichang-Guangshan Expressway is an important part of the national highway planning from Daqing to Guangzhou. № 5 standard section is located in Guangshan County, Xinyang City, Henan Province, starting and ending Stake K51 + 000 ~ K59 + 000, the geological system in the Quaternary middle Pleistocene low liquid limit clay based. The section I built by the tenders passes through the paddy fields with shallow soil and soft soil, poor engineering properties, and most of the sections can not be rolled directly. According to my tenders from the surrounding sand near the rich source of sand, the soft ground for the original fill sand for sand treatment. Good soil quality, high bearing capacity of non-wet foundation, clear table, can be directly filled before rolling. Pass the successful test section, and later construction
