【摘要】 随着我国公路建设的重点逐渐向偏远山区转移,岩质边坡的防护与加固工程成为岩土工程密切关注的问题。结合延庆县刘干路新建工程,建立了路堑边坡在锚杆支护下的二维有限元模型,探讨了边坡支护措施中锚杆长度与锚固角两个变量对支护效果的影响,并根据计算结果提出了最优支护方案。研究结果表明,采用最适锚杆长度与锚固角,可以在尽量减少材料浪费的情况下使边坡安全系数达到较大值,从而确保边坡稳定。更多还原

【Abstract】 With the focus of highway construction in China gradually transferred to remote mountainous areas,rock slope protection and reinforcement work has become a close attention to the issue of geotechnical engineering. Based on the new project of Liugan Road in Yanqing County,a finite element analysis model of cutting slope under anchor support was established. The influence of anchor length and anchorage angle on the support effect is discussed and the optimal support scheme is put forward according to the calculation results. The results show that the slope stability can be fully ensured by using the appropriate length of anchor and anchorage angle with a minimum unnecessary waste of material.更多还原
