1 抗滑稳定验算中的前提条件合理的抗滑验算涉及到各种计算指标的选取,土压力荷载的计算公式的正确选择和安全系数的选取等条件.上述几个前提条件有问题,难以进行合理的挡土墙抗滑稳定验算.1.1设计指标的选取在土压力计算中主要涉及强度指标Φ和C,对于砂性土主要是Φ值,基地摩擦系数f,对小型工程可按有关经验值选取.对于大中型工程应通过试验选取.
1 Prerequisites for anti-sliding stability checking Reasonable anti-slip checking involves the selection of various calculation indexes, the correct selection of the calculation formula of the earth pressure load, and the selection of safety factors. The above several prerequisites are difficult to carry out. Reasonable Retaining Wall Anti-sliding Stability Checking.1.1 Selection of Design Indexes In the calculation of earth pressure, the strength indices Φ and C are mainly concerned. For sandy soils, the main values are Φ, and the base friction coefficient is f. For small projects, relevant experience may be used. Select. For large and medium-sized projects should be selected by test.
