随着社会经济的发展,高速公路成为了影响国民经济的一个重要的交通设施。为此加大投资力度,保障高速公路的完美运行是很有必要的。而在架设高速公路时,地基的加固技术一直是一个难题。经过严格的实验和经验证明水泥搅拌桩可以有效的解决深层地基软弱的问题,并可以满足公路地基的相关要求。本文着重从水泥搅拌桩的加固机理入手,对当前的水泥搅拌桩加固高速公路软弱地基的施工方案做出相关探究。
Along with the social and economic development, the expressway has become an important transportation facility that affects the national economy. To increase investment and ensure the perfect operation of the expressway is necessary. In the erection of the highway, the reinforcement of the foundation has been a problem. After rigorous experiments and experience, cement mixing piles can effectively solve the problem of weak foundation in deep foundation and can meet the relevant requirements of highway foundation. This article focuses on the reinforcement mechanism of cement mixing piles, and makes a research on the current construction plan of cement mixing piles to reinforce the weak foundation of expressway.
