边坡多阶段注浆加固模型
摘要:实践中总结证明注浆法用于边坡加固及滑坡防治是可行的,提炼提出边坡多阶段注浆加固模型。该模型以传统的渗透、充填、压密及劈裂注浆理论为基础,以弹塑性力学中的球形、柱形扩张理论及Boussinesq、Terzaghi理论为指导,推导出多阶段注浆法不同地层及不同阶段的注浆压力、注浆半径及注浆应力分布数学表达式(过程力学模型);用大量试验数据总结出加固后水泥土力学指标统计规律和多阶段注浆加固设计计算模型。多阶段注浆加固模型已在施工项目中得到证实。
Abstract:The feasibility of slope reinforced by grouting is proved and multistage grouting(PG) is put forwatd. Based on the traditional theory of fill grouting, penetration grouting, compaction grouting and hydrofracture grouting, the formula of grouting press,grouting radius and grouting stress of multistage grouting in different phase and stratum is deduced by the introduction of the elastic and plastic theory about glob and column expansion,Boussineq's and Terzagh's theory. The calculation model for multistage grouting design and statistical rule of concrte-clay from a lot of experiment and test data is summarized. The multistage grouting model is testified by the engineering practice.
