当对节理化岩体开挖进行规划时,常遇到的一个问题是:根据节理组的数据和开挖面的方位,如何判别楔体破坏模式。 Hocking和Goodman提过鉴别岩石边坡楔体是沿单面或双面滑动的方法.该法有局限性,仅易于用在楔体滑动可能含有两个平面已预知的情形。本文叙述一种在岩石边坡或地下开挖中,确定四面岩石楔体可能破坏模式的赤平投影法。此法比先前发表的非旋转破坏模式研究方法更有通用性。
When planning the excavation of jointed rock masses, one of the frequently encountered problems is how to determine the wedge failure mode based on the data of the joint group and the orientation of the excavation face. Hocking and Goodman have identified methods for distinguishing rock wedges that slide along one or both sides. This method has limitations and is only easy to use when the wedge slides may contain two planes foreseeable. This paper describes a stereoplanar projection method for determining the possible failure modes of four-sided rock wedges in rock slope or underground excavation. This method is more versatile than previously published research methods for non-rotational failure modes.
