Abstract

Chemical grouting is a technique where solution-based binders are used to improve both mechanical and hydraulic properties of the soils or rocks. The following research shows an extensive laboratory program where a polyurethane and an acrylate were grouted in a tertiary sand under different water contents, relative density, with different gelling time and different grouting conditions. Unconfined compressive strength (UCS), splitting tests, triaxial tests and creep tests on the grouted materials were performed. A statistical interpretation considering the Kernel probability density function was performed in order to understand the interdependency of the changing parameters. In general polyurethane-consolidated samples provide higher mechanical properties with respect to acrylates, however the effects and the dependency to the geotechnical base parameters are different.
丙烯酸酯和聚氨酯树脂灌浆砂的力学性能
化学灌浆是一种使用溶液基粘合剂来改善土壤或岩石的机械和水力特性的技术。在不同含水量、相对密度、不同胶凝时间和不同注浆条件下,对聚氨酯和丙烯酸酯在三级砂中进行了大量的实验研究。对注浆材料进行了无侧限抗压强度试验、劈裂试验、三轴试验和蠕变试验。为了理解参数变化的相互依赖性,采用核概率密度函数进行了统计解释。一般来说,聚氨酯固结样品相对于丙烯酸酯具有更高的力学性能,但是对岩土基础参数的影响和依赖是不同的。
