一、前言 我省舞阳环城改建段计长4.036公里,路基全宽22米,土方工程于1982的由舞阳县组织施工,次年底基层(石灰土结构)仍由该县组织施工。由于路基土含水量大,在底基层施工时,普遍出现软弹现象,无法辗压,工程被迫停工。为摸清情况,经调查测定该段路基土属粉质重亚粘土,液限31左右,塑限15左右,塑指一般在13～17之间,小于0.002毫米的胶粒含量为22.67％,土层0～2米范围内的含水量一般为22％左右,最大
Foreword Wuyang city reconstruction section length 4.036 km, the roadbed full width of 22 meters, earthworks in 1982 by the Wuyang County Organization construction, the grassroots (lime soil structure) by the end of the year is still organized by the county construction. As the subgrade soil moisture content, in the construction of the base, the general phenomenon of soft bullets, can not be rolling, the project was forced to suspend work. To find out the situation, after investigation, the subgrade soil is silty heavy sub-clay, the liquid limit of about 31, the plastic limit of about 15, plastic means generally between 13 to 17, less than 0.002 mm of rubber content of 22.67% Soil water content within the range of 0 to 2 meters is generally about 22%, the largest
