SNS主动柔性防护网在路堑高边坡防护中的应用 总被引:1,自引:0,他引:1
1引言 SNS(Safety Netting System)柔性防护系统是瑞士布鲁克集团1956年研制成功并投入使用的,它以高强度柔性网(钢丝绳网、环形网、高强度钢丝格栅)作为主要构成部分,并以覆盖(主动防护)和拦截(被动防护)两大基本类型来防治各类坡面崩塌落石、风化剥落等地质灾害和雪崩、岸坡冲刷、爆破飞石、坠物等危害的新型柔性防护系统,该系统技术自1995年引入中国以来,已成功应用于铁路、公路、水电站、矿山和市政工程等坡面防护中,同时取得了很好的防护效果。 相似文献

The landslides caused by the 5.12 Wenchuan earthquake resulted in enormous casualties and property losses. Since the earthquake, more than 3,600 landslides have occurred, and 17 of them were catastrophic, each of which has killed more than 30 people. Meanwhile, passive flexible protection has gradually been introduced to resist landslides due to its significant advantages of economy, safety, and environmental protection. To resist landslides effectively, it is necessary to study the load path and design method of passive flexible protection under the action of landslides. In the design of passive flexible protection against landslides, determination of the landslide load is the primary task. In this paper, the formulas of the probability density function and distribution function of the landslide pressure are developed to obtain the value of the accumulated landslide pressure acting on the passive flexible protection, which can be used as the load input parameter in the design of passive flexible protection to resist landslides. Based on the case of the “Shiziliang” potential landslide for the 5.12 earthquake, the pressure data of the landslide are collected, the calculation formulas of the volume, and the pressure of the intercepted landslide are established, and the statistical parameters of the landslide pressure‐loading sample are obtained. According to the Kolmogorov–Smirnov test method, the loading sample of the landslide pressure obeys an extreme‐value type‐I distribution, and then the load model of the landslide pressure is determined. Based on the reliability analysis method, the standard value of the landslide pressure with an over‐95% assurance rate is obtained. These results can provide references for load confirmation to design the passive flexible protection to resist landslides. 相似文献
