【摘要】：基于可靠度理念,提出了巖質(zhì)邊坡經(jīng)濟風(fēng)險分析的基本流程和方法。以某工程料場開挖邊坡為例,利用剛體極限平衡法進行了典型斷面的穩(wěn)定性計算,論證了邊坡支護實施的必要性;基于FLAC3D數(shù)值計算軟件,利用強度折減法擬定了所需支護的最危險滑動通道;通過體系可靠度計算方法對比了不同支護方案的失效概率;基于風(fēng)險損失最小的原則,確定了該巖質(zhì)邊坡較為合理的支護方案。
[Abstract]:Based on the concept of reliability, the basic process and method of economic risk analysis of rock slope are put forward. Taking the excavation slope of a material yard as an example, the stability of typical section is calculated by means of rigid body limit equilibrium method, and the necessity of slope support is demonstrated, which is based on FLAC3D numerical calculation software. Using the strength reduction method, the most dangerous sliding passage of the required support is worked out; the failure probability of different support schemes is compared by the reliability calculation method of the system; based on the principle of minimum risk loss, The reasonable supporting scheme of the rock slope is determined.
