锚杆与喷混凝土结合起来的支护结构——锚喷支护在地下工程中的大量使用,促使人们去探讨它对围岩的支护原理、作用实质和支护效果,进而寻求这种支护形式的设计计算方法。近年来,我国锚喷支护技术发展很快,在各种地下建筑中越来越广泛地采用锚喷支护代替旧式衬砌,不但加速了工程进度而且节约了原材料,对多快好省地修建地下工程起了一定的作用。本文综合介绍一些国内外在这方面的研究情况和观点供设计和施工参考。
Bolting and shotcreting combined support structure - anchor spray support in underground engineering in large-scale use, prompting people to explore its support to the surrounding rock principle, the essence of action and support effect, and then seek this support Prototype design calculation method. In recent years, the technology of anchor and shotcrete support in China has developed rapidly. In many underground constructions, the use of anchor and shotcrete support instead of the old lining is more and more widely adopted. This not only speeds up the construction schedule but also saves raw materials, Engineering has played a role. This article introduces some domestic and foreign research situations and views in this area for design and construction reference.
