山区公路的施工过程,往往采用爆破的方法进行开挖,爆破振动是一个瞬间动力学问题,以数值模拟的方法研究爆破震动波在岩质边坡的传播规律,这对于正确指导和优化爆破施工提供重要依据。本文依托某山区公路工程建设项目,采用数值模拟的方法分析了爆破震动波在边坡介质中的应力场、位移场、速度场等的分布规律,研究了爆破震动效应对山区公路岩质边坡稳定性的影响。现场振动测试结果验证了数值模拟计算的可靠性。
Blasting vibration is an instantaneous dynamic problem during the construction of mountainous highway. Blasting vibration is an instantaneous dynamical problem. The numerical simulation method is used to study the propagation of blasting vibration wave on the rock slope. This is of great importance in guiding and optimizing blasting construction Provide important basis. Based on a project of highway construction in a mountain area, the distribution law of blasting vibration wave in the slope medium is analyzed by numerical simulation. The effect of blasting vibration on the rock slope The impact of stability. Field vibration test results verify the reliability of numerical simulation.
