摘　　要：从间接加筋作用角度出发,通过强化一定范围内土的黏聚力,得到极限平衡状态下加筋土强度表达式。研究表明:当加筋作用影响范围增大时,加筋土的强度会进一步提高,当这种作用满布加筋影响范围时,则加筋土强度的提高会达到极致程度;当加筋材料水平布置时,加筋效果最好。对于砂土,当考虑间接加筋作用时,会有更大的似黏聚力。所得表达式具有普遍适用性。From the perspective of indirect reinforcement,the strength expression of reinforced soil was obtained in the limit equilibrium with strengthening the cohesion of the soil within a certain range.Studies have shown that considering the increase in the influence range of reinforcement,the strength of the reinforced soil was further improved.If the effect covered the influence range of the reinforcement,the increase in the strength of the reinforced soil reached the extreme.When the reinforcing material was arranged horizontally,the effect of reinforcement was the best.For sand soil,when considering the effect of indirect reinforcement,there would be a larger cohesive force.The expressions obtained in this paper have universal applicability.
