本文精测了新疆塔里木北部地区压、张、扭三类不同性质断层断面的起伏高度和长度,利用谢和平及Parisean(1994)的公式,测算了断面分维数D,又由D值测算了粗糙度JRC值,发现压、张、扭三类断层的D和JRC值有明显差别,所取得D值与美国的San An... 本文精测了新疆塔里木北部地区压、张、扭三类不同性质断层断面的起伏高度和长度,利用谢和平及Parisean(1994)的公式,测算了断面分维数D,又由D值测算了粗糙度JRC值,发现压、张、扭三类断层的D和JRC值有明显差别,所取得D值与美国的San Andrees断层的D值具有一定的相似性。 展开更多

Whether the breakdown structure and coding system of construction projects are reasonable or not determines to a large degree the performance level of the entire project management. We analyze in detail the similarities and differences of two kinds of decomposing methods classified by type of work and construction elements based on the discussion of international typical coding standards system designing. We then deduce the differential coefficient relation between project breakdown structure (PBS) and work breakdown structure (WBS). At the same time we constitute a comprehensive construction project breakdown system including element code and type of work code and make a further schematic presentation of the implementation of the system’s functions. 展开更多
