摘要;为了解决废弃轮胎颗粒造成环境污染的问题,我们尝试利用弃轮胎作为建筑材料.其具有质量小减震性能好,吸声强等优点,在减少环境污染的同时还可以在一定程度上降低工程建设成本.对于节约资源.保护环境和可持续发展具有重要意义，植物纤维是一种环境友好型的材料．它不仅具有来源广、可再生、无污染、价格低等优势,而且天然植物纤维较高的强度与较轻的密度轻质、增强土体剪切强度和取材方便等特性,而且低碳环保,促进资源可持续发展，本实验通过单掺和双掺实验表明:掺入轮胎颗粒可以降低土体的质量,但抗压强度也有所下降,掺入适量的(0.25%左右)植物纤维可以提高土体的粘聚力,从而提高土体的抗压强度,这对于今后的工程有一定的参考意义。
Abstract: In order to solve the problem of environmental pollution caused by discarded tire particles, we altempt to use discarded tiresas buildling materials. It has the advantages of small mass， good shock absorption peformance,strong sound absorption, and can reduceenvironmental polluion while also reducing engineering construction costs to a certain extent. I is of greal significance for rsourceconservation, environmental protection, and sustainable development. Plant fiber is an environmentally friendly malterial. lt not only has theadvantages of wide source， renewable,pollution-free and low price, but also has the characterisis of high strength and light density ofnatural plant fiber, enhanced shear strength of soil mass and convenient material collection, as well as low-caton environmental protectionand promotig sustainable development of resources. This experiment shows through single and double mixing experiments that adtling tireparticles can reduce the quality of soil, but the compressive strength also decreases. Adding an appropriale amount of (around 0.25%) plantfiber can improve the cohesion of soil, thereby improving the compressive strength of soil. This has certain reference significance for fultureengineering.
