近来,低质量土壤与固化材料(例如水泥或钢渣)的混合物已用于土方工程。固化材料通过在土颗粒间产生粘结力,改变颗粒级配,可以改善低质土的稠度、抗剪强度、刚度等参数。然而,这些固化材料还含有化学试剂。在这项研究中,模拟降雨入渗与土壤固化材料的混合物建造的路堤进行使用土壤/水/空气/可溶性材料耦合的有限元分析代码,DACSAR-MP_ad。该分析程序不仅可以反映非饱和土结构的变形和渗流,而且可以同时模拟可溶性材料的分散行为。在此,渗透性和降雨强度条件下,并研究其影响。因此,本研究成功地表达了不同降雨条件下路堤内可溶性物质的不同分布。
Recently, mixtures of low-quality soil together with solidification materials, such as cement or steel slag, have been used for earthmoving construction. Solidification materials can improve consistency, shear strength, stiffness, and other parameters of low-quality soil by generating bonding forces between soil particles and changing grain size gradation. However, these solidification materials also contain chemical agents. In this study, simulations of rainfall infiltration into embankment constructed with the soil-solidification material mixture are conducted using the soil/water/air/soluble material coupled finite element analysis code, DACSAR-MP_ad. This analysis code can express not only deformation and seepage for an unsaturated earth structure but can also concurrently model the dispersing behaviour of soluble material. Herein, permeability and rainfall intensity conditions are provided and their effects investigated. Consequently, this study succeeds in expressing different distributions of soluble materials within embankment under different rainfall conditions.
