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、一行锚杆破坏时,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,推导了单(行)锚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 according to the soil layer anchor destruction form by the cement mortar around primarily, on the foundation of the different destruction mass in the soil by supposition of simple anchor, line of anchors destruction, based on geotechnical plastic limit equilibrium theory, has inferred the simple （line） anchor limit supporting capacity formula, this formula result conforms to the project reality, has the certain reference value to the engineering design checking calculation.
