摘要:
滇池泥炭土是一种典型的地域性不良土,对区域内的岩土工程建设有重要影响。文中对滇池流域31个泥炭土工程的数千个地勘资料样本进行分析统计,获得滇池泥炭土空间分布规律。通过引入变异系数筛选泥炭土的分布范围,确定小范围区域内泥炭质土主要物理力学指标的分布规律,分析小区域内各指标随埋置深度的变化情况。文中的研究结果可为局部滇池泥炭土地基工程的设计施工提供可靠的参考依据,文中的研究方法可为其他地区研究地域性土体,为整理地区经验数据提供有利的借鉴作用。
Abstract:
In this paper,the peat soil of Dianchi Lake is a typical regional special soil,which has profound effects on the construction of geotechnical engineering in the region. Thousands of geological prospecting data of 31 peat soil projects in the Dianchi Lake Basin are analyzed and counted to obtain the spatial distribution of peat soil. The distribution and correlation of many physico-mechanical indexes of peat soil were analyzed through the coefficient of variation. The coefficient of variation is introduced to screen the distribution range of peat soil,determine the distribution law of the principal physico-mechanical indexes of peat soil in a small area,the changes of each index in a small area with the embedment depth were analyzed. The research results of this article can serve as a reliable reference for the design and construction of peat soil foundation works in the Dianchi Lake Basin. Research methods can be used to study regional soils in other regions and provide useful references for collating regional experience data.
