山区高速公路隧道洞口段边坡稳定性监测

山区高速公路隧道洞口段边坡工程,在隧道开挖爆破扰动、边坡防护施工、自然降雨等综合因素作用下,容易发生地质灾害。针对此类问题,文章以杭绍台前山隧道洞口段边坡工程为依托,采用现场监测的方法,系统的介绍了边坡稳定性监测的各项内容与监测方法。监测结果显示边坡各项指标变化均符合要求,表明边坡防护合理。对于类似工程可采用相同的监测方法。

The slope engineering of tunnel entrance section of expressway in mountainous area is prone to geological disasters under the action of comprehensive factors such as blasting disturbance of tunnel excavation, slope protection construction, natural rainfall and so on. In order to solve this kind of problem, this paper systematically introduces the contents and methods of slope stability monitoring based on the slope engineering of Qianshan tunnel of Hangzhou-Shaoxing-Taizhou highway. The monitoring results show that all the indexes of the slope meet the requirements, indicating that the slope protection is reasonable. The same monitoring method can be used for similar projects.
