The study on the hardening mechanism of the soft soil with the materials shows that the hardening procedure can be divided into three stages:(1). Hydrating and dissolving stage, when material A and material B of the high-water-content and quick-setting materials respectively dissolve and balance in water.(2). Gel and consolidating stage, when the materials hydrate into calcium crystal and the ion exchange and aggregation of soil particles occur in an alkaline environment.(3). the structure developing stage, when the calcium crystals connect each other, absorb and crystallize the water around; the hydrate remnants, calcium hydroxide, carbonate continuously in water and in the air.
本文对高水速凝材料-软土硬化机理的研究表明,高水速凝材料-软土的硬化过程可分为三个阶段:①水化溶解阶段:主要为高水速凝材料的甲、乙料分别与水的溶解、维持平衡阶段;②胶凝固化阶段:主要为高水速凝材料的水化反应生成钙矾石晶体以及土颗粒在碱性环境中发生离子交换和团粒化作用;③强度增长阶段:钙矾石晶体相互连接,大量吸收周围环境中的水分,并将水分变成自己的结晶水;水化残余物氢氧化钙在水中和空气中发生碳酸化作用。

Rare elements and REE are mainly enriched in gray-black trachyte and less in other rocks. In addition, schistosity, pyritization, silicification and carbonation in gray-black trachyte are contributed to enrich rare element and REE. It is suggested that alkaline rocks in Hongyang area have the characteristics of subvocanics, and alkaline rocks in Hongyang and Miaoya areas all came from upper mantle and mixed with some substances of crust. Intrusion of alkaline rocks is related to the occurrence, development and evolvement of the deep rupture zone in the areas.
稀土、稀有元素主要富集于灰黑色粗面岩中,而在其他岩石类型中相对较少,同时岩石的片理化、黄铁矿化、硅化和碳酸盐化对稀土、稀有元素有进一步的富集作用;提出了本区的碱性岩组合具有次火山岩相的特征,讨论了本区碱性岩的成因,认为其与湖北庙垭地区的碱性岩可能均来自上地幔,并不同程度地混染了大陆壳的物质成分,其形成时代与断裂构造带的发生、发展和演化基本同步。
