加锚直立岩质边坡渐进性破坏模型试验研究

Experimental Study on Progressive Failure of Vertical Rock Slope with Anchor

近年来,随着铁路、高速公路等建设事业的迅速发展,边坡灾害问题越来越突出。同时,锚杆作为一种行之有效的、经济优越的支护,备受人们的关注。本文在Ⅳ类围岩条件下,采用室内模型试验模拟的方法,利用自行设计的实验装置对有锚杆加固的直立岩质边坡的渐进性破坏过程进行研究。由实验结果可知,加锚杆有效的提高了边坡的整体强度,限制了岩体应力的释放,对边坡起到了有效的加固作用,有效的防止边坡失稳而产生的破坏。实验成果的取得,对于实际工程有一定的借鉴价值。

With the rapid development of railway and speedway recently,slope disasters are more and more prominent.At the same time,anchoring as an effective and economical reinforcing method,attracts more and more attention.Based on the in-door model test simulation,the progressive failure of vertical rock slope of Grade IV according to China classification and reinforced with anchors is studied by an own design test apparatus.From the result of the test we can find that the slope stability is enhanced and the release of rock stress is confined by adding anchors,the slope is reinforced and the failure due to instability can be prevented effectively.The test results can be as reference for practical projects.
