摘要
在软弱的超高陡坡支护施工中,通过对陡坡段悬挑型钢的锚固受力机理的分析并采用保证安全性的施工措施,比选了合理的脚手架方案。对陡坡段脚手架与山体的连接件的截面、锚固长度、施工工艺、固定方法进行深入研究,隔离了上部缓坡段对下部陡坡段的荷载作用,同时阐述了缓坡段悬挑型钢及连接件施工,有效地解决了该类复杂岩土条件下脚手架难施工易倒塌的问题。
Reasonable scaffold scheme was selected in supporting engineering of highly steep weak slope. Anchorage stress mechanism of cantilever type steel beam was analyzed and the construction measures of safety were used. Section, anchorage length, construction technology and fixed method of connection between scaffold of steep slope and hilly mass were intensively studied. Loads between upper gentle slope scaffold and lower steep slope is isolated. The construction of cantilever type steel beam in gentle slope and connection was described. The problems of construction challenge and easily collapsed in complicated geotechnical conditions were effectively solved.
