摘要
通过对莱州湾青东5区块1#人工岛进海路路由区的以往调查资料的收集和对该区进行工程地质勘察,分析了该区的主要工程地质条件,进一步讨论得出影响该区工程稳定的主要工程地质问题为:地层垂向上软硬互层分布的地质结构;在基本烈度为8度和9度的地震作用下,路由区所有的粉土层均有发生液化的可能;研究区的地形起伏过大,影响工程的稳定性。根据讨论所得工程地质问题,对该区的工程建设安全提出合理建议。
The research area is located in the 5th block of Qingdong area around the sea access to the 1 ^# artificial island in the west coast of the Laizhou Bay. After the study of engineering geological con-ditions of the area based on precious survey and engineering geological data, there are some key engi-neering geological problems which must be carefully taken into account. First, the vertical sequence of interbeded clay and silt bears the risk of sand and silt liquefaction if an earthquake of intensity of 8 or 9 shocks this region. Second, the large topographic differences will be too risky to ground stability. Recommendations and suggestions are made for consideration of the designers.
