【摘要】 以宜昌国家粮食储备库工程边坡防失稳设计及施工为例 ,介绍了交错布置长短锚杆加固边坡的技术 ,该技术有利于改善岩土力学性能和提高锚杆的锚固力。对施工所用喷射混凝土在保证设计标号的前提下尽量减少石子用量 ,可减少喷射回弹率 ;按螺旋形轨迹进行喷射 ,可有效消除混凝土固化前的下坠和滑移现象。更多还原

【Abstract】 By taking the hill side slope stabilization construction project of a grain reserve depot as an example, the hill side reinforcement technique by using of staggering layout anchor bars of different length is introduced. This technique will improve the soil and rock mechanics and enhance and anchoring ability. During construction, the addition quantity of aggregate may be reduced if the concrete strength can be guaranteed, which will reduce concrete rebounding, and by using spiral jetting method, the possibility of concrete sagging and sliding prior to its setting can be effectively eliminated.\;更多还原
