高速公路路基高液限黏土施工改良技术

近年来,高速公路工程建设在全国范围内的各省市都取得了长足的发展,但中国幅员辽阔,各地都有不同的地质情况,不同的地质条件下,采取的技术措施也随之不同,不同的技术措施,其在环保、经济、质量、工效、资源配置等方面的效果都是不同的。如何经济节约、保质保量、绿色环保地修建好高速公路是广大工程人员共同面对的课题。文章就比较典型的高液限黏土在高速公路路基中的改良方法展开研究,结合在建国家高速公路网昆明绕城东南段现场高液限黏土进行取样试验分析,采用不同改良方法对高液限黏土进行改良处理,结合改良试验结果浅谈高液限黏土改良技术,对类似工程提供借鉴和参考。

In recent years, highway engineering construction in all provinces and cities throughout the country has made consid-erable progress, but China has a vast territory, so there are different geological conditions everywhere with different geological condi-tions. Different technical measures have different effects on environmental protection, economy, quality, efficiency, resource allocation and so on. How to build a good highway in an economical, quality and quantity-oriented, green environment-friendly way is a com-mon task faced by the majority of engineers. In this paper, the improvement method of high liquid limit clay in expressway subgrade is studied, and the sampling test of high liquid limit clay in the southeast section of Kunming City around the city of the national highway network is carried out. Using different improvement methods to improve the high liquid limit clay, and based on the results of the improvement test, it discusses the high liquid limit clay improvement technology, in order to provide reference for similar pro-jects.
