护坡是河道工程中量大面广、保证堤防安全的重要基础设施。以实际工程——沈阳市鸟岛公园铰接式混凝土砌块护坡为例,利用毕肖普条分法和强度折减法计算了29°坡度角、作用于45k砌块时该护坡的稳定安全系数。基于这两种方法,进一步详细讨论了砌块质量与坡度角发生变化时护坡的稳定系数,随着坡度和砌块质量增加,护坡稳定安全系数逐渐减小,但强度折减法结果准确度更好。
The slope protection is an important infrastructure of the enormous quantity and ensure the safety. Take the actual project-- Shenyang City Park Hinge the Joint Concrete Block Slope,as an example,use of Bishop Slice method and Strengthen reduction method , calculated by 29 degree slope angle,45 kg block the effect slope stability factor of safety.Based on two methods, further calculated slope stability and safety coefficient with different slope angle and concrete block weight ,it is showed that the stability of slope is reduced with the increase of the different slope angle and blocks.More accurate results can be obtained by strengthen reduction method.
