应用于治理桥头跳车的泡沫轻质土性能研究

Research on the Performance of Foamed Light Soil Treating Abutment Jump

摘要: 桥头跳车是目前公路建设中常见的通病之一，严重影响了行车舒适性，降低了车辆的行驶速度和道路的通行能力，是道路交通安全的重要隐患之一，损害了公路的社会效益和经济效益。本文在大量泡沫混凝土相关文献的基础上，结合已有成果，围绕治理桥头跳车开展了一系列试验研究工作。首先，确立了泡沫轻质土的几种可行的基准配合比。其次，通过实验探究了其强度与水稳定性，确定各因素对其性能的影响规律。

Abstract: The abutment jump is one of the common problems in highway construction, which seriously affects the driving comfort, reduces the vehicle’s traveling speed and the capacity of the road. It is one of the important hidden dangers of traffic safety and damages to the highway society and economic benefits. Based on a large number of relevant literatures on foam concrete, this paper combines a number of existing achievements and carried out a series of experimental studies around the management of bridgehead jumping. First of all, it establishes several feasible mix proportions. Secondly, it explores the strength and stability of water experimentally, and determines the influence of various factors on its property.
