Abstract

Joints are planar tensile opening-mode fractures whose relative motion, as the fracture propagates, is perpendicular to bedding plane and occur in a systematic manner to form a joint set. This paper discusses the mechanical control of joint propagation, the relationship between join spacing and layer thickness, the join saturation, the frequency distribution of join spacing, the joint density, the cross joint, and the development mechanism of joint from a lot of recent joint studies in sedimentary rocks.

절리는 전파할 때 상대적인 이동이 절리 벽에 수직으로 일어난 평탄한 신장 열림 모드 단열이다. 층상 퇴적암에 발달하는 절리는 일반적으로 층리면에 수직이고 인접한 절리와 평행한 배향과 규칙적인 간격을 가지며 절리 조를 이룬다. 본문은 층상 퇴적암의 절리에 대한 최근 연구 결과들을 토대로 절리 전파의 역학적 규제, 층두께-절리간격의 관계, 절리 간격의 빈도 분포, 절리 포화, 절리 밀도, 교차 절리, 절리 발달 기구 등을 고찰 한다.
