【摘要】 西安地裂缝与地面沉降研究，自８０年代初至今已有１０余年的历史，现已取得了一系列重要共识，同时也还存在某些分岐。本文从地裂与地面沉降研究现状、致灾机理、灾害防治对策和措施等主要方面作了研讨。其中特别强调了制定防治地裂缝与地面沉降灾害对策和措施必须遵从其致灾机理差异性特点的重要意义。更多还原

【Abstract】 Since the early year of the 80s, the research on geofracture and land subsidence have lasted for more than ten years. Now a series of significant common knowledge were obtained, but there are some divergences on this question. This paper discussed main aspects-present conditions of research on geofractures and land subsidences, hazard-forming mechanisms, countermeasures and measures of controlling hazard. It was specially stressed in this paper that establishment of countermeasures and measures of controlling geofracture and land subsidence hazard must abide by characters of the difference in hazard-forming.更多还原
