Marine facies soft soil similar material for tunnel instability failure model test and preparation method of marine facies soft soil similar material
The invention belongs to the field of underground engineering, and relates to a marine soft soil similar material for a tunnel instability failure model test and a preparation method of the marine soft soil similar material. The marine soft soil similar material comprises the following components in parts by weight: 95-105 parts of soft clay, 11-30 parts of expansive soil, 8-12 parts of silicone oil and 3-6 parts of washing powder. A plurality of common materials in different fields are adopted and organically combined through a basic geotechnical experiment, the soft clay determines the permeability of the materials, the expansive soil improves the permeability and strength of the materials, and the silicone oil improves the cohesive force of the materials; the permeability and the strength are regulated and controlled through expansive soil so as to meet experimental requirements and mechanical properties; the model experiment is carried out by matching marine facies soft soil with different permeability, and a series of reasonable proportions are obtained through a large number of basic experiments, so that the similar material can simulate the field condition of the tunnel construction process, can meet the mechanical and deformation characteristics of the marine facies soft soil, uses local materials, and is convenient and economical.
本发明属于地下工程领域，涉及一种用于隧道失稳破坏模型试验的海相软土相似材料及其制备方法。所述海相软土相似材料，包括按重量份数计的如下组分：软黏土95‑105份，膨胀土11‑30份，硅油8‑12份，洗衣粉3‑6份。本发明采用多个不同领域的常用材料，并通过基础土工实验使其有机结合：软黏土决定材料渗透性，膨胀土改善材料渗透性与强度，硅油提升材料粘聚力；通过膨胀土调控其渗透性和强度以满足实验要求和力学性质；配比不同渗透率的海相软土进行模型实验，并通过大量基础实验，得出了一系列较为合理的配比，使得相似材料既能模拟隧道施工过程的现场情况，又能满足海相软土的力学及变形特性，就地取材，便利节约。
