91—16—4,岩石锚杆护坡工程——河合初男[日];《水利水电快报》日本田川坝坝址右岸的高边坡是具有开口裂隙的裂隙型凝灰角砾岩,采用混凝土框和岩石锚杆护坡,确保上下作业的安全,且可迅速处理坡面动态观测资料的装置。基于这两点考虑,开挖边坡采用了临时张拉和锚固(一次张拉),从而缩短了工期。同时利用微机对坡面进行24小时的自动观测管理。本文详细地介绍了护坡工程设计及施工过程。田川
91-16-4, rock bolt slope protection works - Kawai first male [Japan]; “water conservancy and hydropower Express” Tianchuan dam site on the right bank of the high slope is a fractured open-cut gravel breccia, the use of concrete Box and rock bolt slope protection, to ensure the safety of operations up and down, and can quickly deal with slope dynamic observation device. Based on these two considerations, temporary tensioning and anchoring (one-time tensioning) of the excavated slope is used, thereby shortening the construction period. At the same time using the computer on the slope for 24 hours of automatic observation management. This article describes in detail the slope protection engineering design and construction process.
