山区软弱路基换填处治研究

Study on the Treatment of Soft Subgrade in Mountainous Area

目前,换填法在东部沿海地区获得了重要的研究成果,但对于山区软弱路基换填的研究工作较少,工程中常借鉴其他地区的实践经验。因此论文对山区软弱路基的换填展开相关的研究工作。通过研究山区地形地貌、软弱土存在形式、工程特性、土层分布及路基与软弱土层的位置关系,从路基工程特性出发,分析了影响换填处治方法选择的影响因素,给出了各种换填处治适合处理的工况,并进行了总结。

At present, the method of land reclamation has obtained important research achievements in the eastern coastal areas, and the research work on the weak roadbed in mountainous areas is less, and the practical experience of other regions is often used in the project. Therefore, this paper has carried out research work on the replacement of weak subgrade in mountainous area. Based on the study of the terrain and topography of mountainous areas, the existence of weak soils, the engineering characteristics, the distribution of soil layers and the location relationship between the subgrade and the weak soils, and the characteristics of the roadbed engineering, the factors influencing the selection of the dressing are analyzed, and the main factors, Given a variety of dressing treatment for processing conditions, and finally summed up.
