摘要
嵌入型危石在山区公路边坡广泛发育,严重影响了山区公路边坡的稳定性。根据嵌入型危石的受力情况建立了危石稳定性分析的力学模型,运用极限平衡理论建立了稳定性分析方法,受力比较明确,所需要的计算参数较少。以国道316某处边坡嵌入型危石为实际算例,计算结果表明该方法能基本反映嵌入型危石的实际稳定状况。
Being wide distributed, the embedded critical rocks affect the stability of the slope along highway in mountainous area. The mechanical model of the critical rock is established based on its force condition. On the basis of limit equilibrium theory a stability analysis method which has the advantages of stressing definite and less calculation parameters is established. Taking the critical rock of the slope along national highway 316 as practical calculation example, the results show that the established stability analy- sis method can basically reflect the real stability state of the embedded critical rock.
