随着经济社会的不断发展,工程项目开展区域逐渐增多,在各种地质区域内的工程活动也随之增多,膨胀土地区也不例外。作为一种严重破坏工程质量的粘性土,膨胀土将严重损坏工程结构物。为在膨胀土分布广泛地区进行公路工程活动,必须合理整治膨胀土。为此,本文在充分了解水泥改良膨胀土作用机理的前提下,结合具体工程案例,提出了相应的试验方案,以此规范膨胀土填芯路基施工工艺,全面提升工程施工质量。
With the continuous development of economy and society, the number of projects carried out by the project areas has gradually increased, and the number of engineering activities in various geological areas has also increased. Expanded land areas are no exception. As a cohesive soil that seriously damages the quality of the project, expansive soil will seriously damage the structure of the project. In order to carry out highway engineering activities in widely distributed areas of expansive soils, expansive soils must be properly rehabilitated. Therefore, under the premise of fully understanding the mechanism of the expansive soil with cement, this paper puts forward the corresponding experimental scheme based on the specific engineering case, so as to standardize the construction technology of the expansive soil filled core embankment and comprehensively improve the construction quality.
