摘要

椰壳纤维是一种前景广阔的天然纤维，可通过纤维加固来稳定土壤。本文进行了增重、吸水率降低和单纤维拉伸强度测试，以评估楝树油、煤油和腰果壳油（CNSL）等不同天然制剂在改善棕纤维机械性能和耐久性方面的应用。对固化 3 天、28 天和 180 天的土壤试样进行了三轴测试，以确定使用经不同药剂处理的椰壳纤维加固后，土壤试样的剪切强度有何改善。纤维加固通过改善内聚力和摩擦角，提高了土壤的抗剪强度。在使用的不同药剂中，发现 CNSL 是最有效的椰壳纤维处理药剂。

Shear Strength Behavior of Clayey Soil Reinforced with Natural Agent-Treated Coir Fiber

Coir is a promising natural fiber that can be used for soil stabilization through fiber reinforcement. In this paper, weight gain, reduction in water absorption, and single-fiber tensile strength tests are performed to evaluate the application of different natural agents such as neem oil, kerosene, and cashew nutshell liquid (CNSL) in improving the mechanical properties and durability of coir fibers. Tri-axial tests are performed on soil specimens cured for 3, 28, and 180 days to determine the improvement in their shear strength when reinforced with coir fibers treated with different agents. The fiber reinforcement led to an increase in the shear strength of the soil by improving cohesion and friction angle. Among the different agents used, the CNSL is found to be the most effective agent for coir fiber treatment.
