公路灌浆法是把灌注材料通过钻孔或路基塌陷处的出口进行灌浆,其目的是强化土层、充填洞隙、拦截地下水流、加固地基。灌浆法加固技术的应用领域很广泛,已广泛应用于铁路、公路、市政工程、港口码头等行业的软土地基加固中。国外对公路塌陷病害的处治已初步建立起有针对性的理论分析方法,其中最近距离法、泊松分布函数计算法、双重付里叶级数分析法等方法对公路塌陷的预测研究和处治起到了理论指导作用,但这些方法还不完善。国内在公路塌陷危险性数学评价理论方面做了一些研究,公路灌浆法就是一种新的施工技术。该技术可节约工程投资、提高工程质量、减少道路维护费和车辆事故。
Highway grouting method is to pour the material through the borehole or subgrade collapse outlet for grouting, the purpose is to strengthen the soil, fill the hole, intercept groundwater flow, strengthen the foundation. Grouting reinforcement technology has a wide range of applications, has been widely used in railway, highway, municipal engineering, port and other industries in the soft ground reinforcement. The treatment of road collapse in foreign countries has initially established a targeted theoretical analysis method, of which the recent distance method, Poisson distribution function calculation method, the double Fourier series analysis method of road collapse prediction and treatment To the theoretical guidance, but these methods are not perfect. Some domestic researches on the mathematical evaluation theory of dangerous road collapse have been made. The highway grouting method is a new construction technique. The technology can save engineering investment, improve project quality, reduce road maintenance costs and vehicle accidents.
