温孟滩区土的工程特性评价与毛管性试验研究

为了防止滩区土的毛管性对黄河小浪底水利枢纽移民房屋产生不利影响 ,实地调查了温孟滩区新旧房屋的地基处理、基础型式、村台高度、使用现状、滩区地下水埋深等 ,重点对滩区土的工程特性进行了有关项目的土工试验、毛管水上升高度试验研究 .结果表明 :滩区土的工程特性较差 ,毛管水上升高度达 3 .12m ,为此 ,提出安置区移民房屋建筑时 ,必须对地基进行处理 ;减小基础和地圈梁相连的户数 ;村台高度大于 1.2m等等

Evaluation for the Engineering Properties of Soil and Experimental Researches on Capillarity in Wenmeng Bottomland

To avoid disadvanta geous effects of the capillary water in Wenmeng bottomland on the immigration building of the yellow River Xiao langdi water conservancy pivot,fieldworks for ground treatment,foundation form,thickness of bedding cushion and status quo of the new and old buildings and ground water table in the Wenmeng bottomland receiving area for immigrants of the Yellow River Xiaolangdi water conservancy pivot are carried on,and soil tests and experiments of the risen height of capillary water about soil in this area are emphatically performed and studied. The results of the investigations and researches show that the engineering properties of the Wenmeng bottomland soil is not good,with the risen height of capillary water amounting to 3.12 metres.Based on that,when the building construction in this area is carried,first,ground must be treated and secondly,foundation and beam must be reduced,third,over 1.2 metres thickness of bedding cushion is setted.
