公路软土路基的处理研究

公路软土路基的处理讨论公路软土路基的处理讨论 摘要：随着现代经济的迅速进展，对公路交通运输的需求大大提高，我国公路建设有了突飞猛进的进展。我国地域辽阔，公路建设过程中路基所处地质情况复杂多变，软土路基、冻土路基等都加大了公路施工过程中质量控制的难度。加快对公路路基处理的讨论有利于提高我国公路施工的工程质量，本文主要对公路软土路基的处理进行讨论分析。根据软土路基所处位置、路基厚度以及生成原因等方面的不同，可以分别采纳置换法、表层处理法、竖向排水法、加载法以及桩路基加固法等进行软土路基处理。本文介绍了软土的定义及其工程性质，概括了软土路基的特性，明确指出了路基施工质量的重要性，进而从常见的软土路基破坏形式出发，详细阐述了不同情况下的处理方法。 关键词：软土；工程性质；公路软土路基；处理方法；施工；质量 Abstract: with the rapid development of modern economy, the demand for road transportation is greatly increased, the highway construction in our country have developed by leaps and bounds. China's vast territory, the highway construction of subgrade in the process of the geological condition is complicated, the soft soil roadbed, frozen soil subgrade, etc have stepped up the difficulty of the highway construction process quality control. To speed up the study of highway subgrade treatment to improve engineering quality of highway construction in our country, this paper mainly for highway soft soil subgrade treatment by research and analysis. According to the soft soil roadbed subgrade thickness and the location, the reasons of different, can be respectively by the methods of displacement method, surface treatment, vertical drainage method, loading method and pile foundation reinforcement method for soft soil subgrade treatment. This paper introduces the definition and its engineering properties of soft soil, summarized the characteristics of the soft soil roadbed, clearly points out the importance of the ro...
