Application of open-mouth curtain protection net in the treatment of high rock slope

China Nonferrous Metals Industry Xi’an Survey Design & Research Institute Co., Ltd., Xi’an 710054, Shaanxi, China

摘要

摘要: 张口式帘式防护网具有技术针对性强、施工运行周期短、建设成本较低、防护效果明显等优势，在岩质崩塌治理领域应用广泛。依托陕西省榆林市府谷县某崩塌治理工程，从工程地质条件及形成原因对该崩塌进行分析与评价，借助Rockfall软件对坡面落石运动状态进行模拟计算，提出了局部主动防护网加固+张口式帘式防护网引导+坡脚被动防护网拦截的综合治理方案，与其他方案对比可节省预算约200万元，经济效益突出，实践表明该治理方案防护效果良好，对落石、滚石达到100%拦截，可为类似岩质高边坡崩塌治理工程提供一定的借鉴。

Abstract: Open-mouth curtain protective net has been widely used in rock collapse control because of its advantages such as technical pertinence, short construction period, low construction cost and obvious protective effect. Based on a landslide treatment project in Fugu County, Yulin City, Shaanxi Province, this study analyzes and evaluates the landslide from the engineering geological conditions and causes, and simulates the movement state of rockfall on the slope with Rockfall software. A comprehensive treatment scheme of local active protective net reinforcement+open-mouth curtain protective net guidance+passive protective net interception at the foot of the slope was applied. Practice shows that this treatment scheme has good protective effect, and can intercept rockfall and rolling stones 100%, which can save about 2 million yuan compared with other schemes. It can provide some reference for similar high rock slope collapse treatment projects.

表 4 各方案优缺点对比

	技术难点	安全防护效果	经济效益
方案一	当坡面整体采用主动防护网治理时，由于坡面整体分布破碎层且层厚较厚，需在整个坡面大面积布置主动防护网，并用较长锚杆配合主动网防护网进行加固	由于坡面整体被主动网覆盖住，坡面防护基本达到100%，防护安全性极高	308.59万元，经济效益较差
方案二	当坡面采用被动防护网拦截时，由于坡面坡形上陡中缓下平的特殊性，需在坡面上布置三道及以上防护网，对于现场施工挑战较大	被动网防护受坡面起伏影响较大，高处防护网落石难以清理，易行成新的安全隐患，防护效果一般	120.97万元，约为方案一估算0.4倍，经济效益良好
方案三	适宜本工程高边坡特性，针对高边坡上部带状发育危岩体进行主动防护网加固，张口式帘式防护网沿坡面布置，消耗上、中部潜在掉落危岩动能，下部被动网靠近坡脚，施工较为简单便捷	上部危岩带被主动网全覆盖，中下部采用张口式帘式防护网+被动网方式，基本保障危岩100%不落地，防护效果良好	110.03万元，约为方案一估算0.35倍，经济效益优秀
