摘要
根据土层锚杆的破坏形式通常以水泥砂浆周围土层发生剪切破坏为主,在假设单根锚杆、群锚杆破坏时土体中形成不同的破坏体的基础上,基于岩土塑性极限平衡理论,推导了群锚杆极限承载力计算公式.该公式计算结果更符合工程实际,对工程设计验算具有一定参考价值.
Usually the soil layer has the shearing failure as a soil layer anchor destruction form around the cement mortar. Suppose different destruction masses forms in the soil of simple anchor, group anchorage destruction. Based on geotechnical plastic limit equilibrium theory, we worked out a simple (line) anchor limit bearing capacity formula, the result of which conforms to the project reality, and has certain reference value to the engineering design checking calculation.
