【摘要】 笔者基于对新疆国道 2 18线和省道 313线道路翻浆的长期现场观测和研究 ,比较客观地构筑了道路翻浆发生的物质环境 ,即路床中 4 0 %左右的粘土含量和 2 5 %左右的含水量 .道路翻浆可以分为气候翻浆和动力翻浆两大类型 ,路床中存在粘土透镜是翻浆发育的必备条件 .翻浆鼓丘是道路翻浆的直观体现 .翻浆鼓丘呈椭圆形及圆形 ,椭圆形鼓丘主要出现在平直公路段 ,圆形鼓丘主要出现在弯曲公路段 .路基中道路翻浆通常发生在路面基层以下 30— 4 0cm的路床范围内 .根据鼓丘龟裂纹可以反演翻浆类型 ,并判识粘土透镜的位置 .更多还原

【Abstract】 Based on investingations in situ to highway tympanites along G218 and G313, the authors found reasonably maeterial environment for highway tympanites to develop in this paper, i.e clay content is 40% or so while water content is 25% or so. Highway tympanites can be classified into two types: climate tympanites and dynamic tympanites. Tympanites pingo are shown for highway tympanites to occur. Tympanites pingo are circle in crankle road and tympaites pingo are ellipse in longitudinal road. In the section of roadbase, tympanites pingo often form below 30 or 40 centimeter of road surface. According to tympanites pingo crack, we can identify the type of tympanites and scale and depth of clay lens.更多还原
