| 摘 要： | 随着我国经济的快速发展,基础设施发展迅速,建设过程中新的施工技术层出不穷,其中对于工程岩体分化严重、结构面较发育的高挖方边坡,通常采用锚杆框架梁结构支护。然而,对于高山滑雪中心滑雪赛道两侧高陡边坡,除了要实现边坡稳定的同时还需考虑如何防止雪道污染的问题。本文结合北京2022年冬奥会高山滑雪中心第二标段的工程实践,详细阐述了兼具边坡支护和防止雪道污染的锚杆框架梁支护体系的设计原则、设计内容、施工工艺,并说明了施工中的一些细节或要点。实践证明该支护体系合理,不仅确保了边坡的安全稳定和防止了雪道污染,同时具有造价低、施工机动性强的特点,可以在类似的雪道施工中推广。

| Abstract: | With the rapid development of economy,China s infrastructure has developed rapidly,and construction techniques have emerged one after another in the construction process.For high excavated slope with serious rock mass differentiation and well-developed structural plane,bolt frame beam structure is usually used.However,for the high slope on the side of the ski course in the alpine skiing center,the slope stability and pollution prevention of ski slopes should both be taken into consideration.In this paper,based on the engineering practice of the second section of the alpine skiing center of Beijing 2022 Winter Olympic Games,the research elaborates the design principles,design contents and construction techniques of the support system of anchor frame girder,and explains some details or key points in the construction.Practice has proved that the rationality of the support system not only ensures the stability of the slope and clean of the trail,but also has the characteristics of low cost and strong construction flexibility,which can be popularized in similar snow track construction. |
