阳西县陂底水库边坡爆破开挖响应机理及生态防护措施分析

Analysis on Response Mechanism and Ecological Protection Measures of Highway Slope Blasting Excavation

采用数值模拟方法分析边坡在不同开挖方式下的安全系数,静态开挖下,边坡安全系数大于1.20,稳定性较好;当存在爆破荷载时,边坡安全系数会随着爆破荷载变化,距离爆破荷载位置越远,位移响应越明显,在施工过程中应严格施工,减少对边坡的扰动;同时,针对不同类型的边坡,建议采用不同的生态护坡工程,可保证工程稳定和环境协调性。

The safety factor of slope under different excavation methods is analyzed by numerical simulation method.Under static excavation,the safety factor of slope is greater than 1.20,and the stability is better;when there is blasting load,the safety factor of slope will change with the blasting load,and the farther away from the blasting load,the more obvious the displacement response.Therefore,strict construction should be carried out in the construction process to reduce the disturbance to the slope At the same time,for different types of slope,it is suggested to adopt different ecological slope protection projects to ensure the stability of the project and environmental coordination.
