环渤海地区港口建设中的环境工程地质问题

Problems on Environmental Engineering Geology in Port Engineering Construction in the Bohai Rim Region

环渤海地区地壳稳定性较差,沿海地带软土地基、沙土液化等不良工程地质问题较多,存在崩塌、滑坡、侵蚀淤积等环境地质灾害。特别是由地下水开采引起的地下水位下降漏斗、地面沉降、海水入侵等灾害严重。本文章介绍了环渤海港口工程地质环境,并就原生地质环境、次生地质环境、人为地质环境对港口建设的影响进行论述。

Many infaust engineering geological problems and geological hazards,such as poor crustal stability,soft soil foundation in the coastal zone,sand liquefaction,collapse,landslide siltation,erosion,storm surge and so on,are present.Especially,the drawdown funnel caused by underground water mining,the land subsidence and the seawater intrusion are the most serious in China.These all make the Bohai Rim Region be the largest and the most serious geological disaster area in China.The port engineering geological environment in the Bohai Rim Region is introduced and the effects of the original geological environment,the secondary geological environment and the artificial geological environment on the port construction are discussed.
