融河高速公路炭质岩特性与路堑边坡防护对策

对广西融水至河池高速公路沿线路堑边坡炭质岩工程特性进行研究，阐述了炭质岩的物质组成、物理力学指标，分析其强度变化与路堑边坡破坏机理关系。进行有机硅固化剂封闭坡面和喷混植生防护试验，固化剂对降低炭质岩的亲水敏感性和保障边坡稳定具有一定效果，较传统防护措施更容易实现生态修复。

Characteristics of Carbonaceous Rock and Protection Measures of Cutting Slope along Rongshui—Hechi Highway

The engineering characteristics of carbonaceous rock of the cutting slope along Ronghui-Hechi highway in Guangxi were studied herein in such manner that the substance composition, the physical and mechanical indexes were described, and the relation between the strength of rock and the failure mechanism of cutting slope was analyzed. The tests of organic silicon curing agent for slope surface sealing and spray sowing for slope protection were conducted, where the curing agent has a certain effect on reducing the hydrophilic sensitivity of carbonaceous rock and ensuring the stability of slope. As a result, it is easier to realize ecological restoration than traditional protective measures.
