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.
