摘要
利用有限元方法对土钉支护的极限高度进行了研究。利用地基极限承载力的求解思路来求得极限高度,研究了复合土体的弹性模量、粘聚力、内摩擦角、土钉长度等主要因素对土钉支护极限高度的影响,对在匀质土体的情况下与土塑性力学中的理论解进行了比较,结果比较吻合。
This paper studies the height under ultimate load of soil-nail support using finite dement method, solves the height with the concept of ultimate bearing capacity of foundation, studies the factors influenced the height from elastic modulus of composite soil, cohesion, internal friction angle and the length of soil-nail, and compares the theoretical solution under the condition of homogeneous soil and that in soil plasticity theory, which are tallies with each other.
