莱州湾海岸带工程地质分区及其特征

依据莱州湾海岸带海陆统筹综合地质调查取得的实测数据，并结合前人对该区的工程地质研究成果，综合考虑地形地貌、地质构造、岩土体工程地质类型及特征，将研究区陆域部分划分为3大工程地质区，即鲁西北平原工程地质区(Ⅰ)、鲁中南中低山丘陵工程地质区(Ⅱ)和鲁东低山丘陵工程地质区(Ⅲ)。在综合归纳莱州湾海域工程地质条件基本特征的基础上，按其相似性和差异性，将研究区海域部分划分为3大工程地质区，即鲁东滨海平原工程地质区(Ⅳ)、西部黄泛平原及滨海平原工程地质区(Ⅴ)和莱州湾中部堆积平原工程地质区(Ⅵ)。

DIVISION OF ENGINEERING GEOLOGICAL ZONES FOR COASTAL ZONE OF LAIZHOU BAY

Based on the results of integrated geological survey recently acquired from the coastal zone of the Laizhou Bay, combined with the previous achievements of engineering geological studies, and taking topography and geomorphology, structural geology, lithology and soil engineering geology into consideration, the land part of the study area is divided into three engineering geology zones, namely the northwest Shandong plains engineering geology zone (Ⅰ), the low mountains and hills engineering geology zone (Ⅱ), east Shandong hilly area engineering geology zone (Ⅲ). For the offshore area of the Laizhou Bay, there are also three engineering geology zones, i.e. the coastal plain of eastern Shandong engineering geology zone (Ⅳ), western Yellow River flood plain and coastal plain engineering geology zone (Ⅴ) and the central sedimentary plain of the Laizhou Bay engineering geology zone (Ⅵ). Features of the zones are described in this paper.
