摘要
城市建成区的工程建设对原始地形的改造剧烈,而传统的钻探、原位测试或物探等勘察手段的局限性较大,通过这些方法往往无法得知工程建设区所处的原始地形地貌,同时密集的城市建筑及市政设施限制了钻孔布设数量和范围。文章基于查阅老地形图的城区地形地貌演变过程推测方法,结合现场工程地质条件与标高,实现了对于城市复杂区域地层分布的有效推测,优化了钻孔布置方案,一定程度上弥补了其他勘察手段的限制,并基于地形改造历史揭示了可能的施工风险。
The engineering construction of urban built-up areas has undergone drastic transformation of the original terrain,while traditional exploration methods such as drilling,in-situ testing,or geophysical exploration have significant limitations.These methods often fail to determine the original terrain and topography of the engineering construction area.At the same time,the dense urban buildings and municipal facilities limit the number and scope of drilling arrangements.The article is based on the method of inferring the evolution process of urban terrain and geomorphology by consulting old topographic maps,combined with on-site engineering geological conditions and elevations,to effectively speculate on the distribution of strata in complex urban areas,optimize the drilling layout plan,to some extent compensate for the limitations of other investigation methods,and reveal possible construction risks based on the history of terrain transformation.
