| 摘 要： | 地面沉降地质灾害在鲁北平原发展日益严重，制约着重大工程建设和社会经济发展。本文通过分析区内第四纪沉积展布特征，结合二等水准测量数据和分层沉降标数据与地面沉降规律，揭示鲁北平原区地面沉降机理和沉降模式，为同类型地区进行参考借鉴。①鲁北平原地面沉降主要贡献层为中更新统地层，滨州140～320m地层沉降量约占总沉降量的62%。②依据沉积相、沉积成因、地层结构、地面沉降驱动机制等因素，鲁北平原地面沉降可分为山前冲积、洪积平原模式、黄河泛滥冲积平原模式、三角洲冲积、海积平原模式三种模式。

| Abstract: | Ground subsidence geological hazards are becoming more and more serious in North Shandong Plain, which restricts the construction of major projects and social and economic development. Based on the analysis of the distribution characteristics of Quaternary sediments, combined with the second- class leveling data and stratified subsidence scale data and the law of land subsidence, this paper reveals the mechanism and mode of land subsidence in the North Shandong Plain, which can be used as a reference for similar areas. (1) The main contributing layer of land subsidence in the North Shandong Plain is the Middle Pleistocene stratum, and the subsidence of 140~320 m stratum in Binzhou is about 62% of the total subsidence. (2) According to sedimentary facies, sedimentary origin, stratigraphic structure and driving mechanism of land subsidence, land subsidence in North Shandong Plain can be divided into three models: piedmont alluvial model, flood plain model, Yellow River flood alluvial plain model, delta alluvial model and marine plain model. |
