珠江三角洲入海口工程地质单元层探讨

On engineering geological unit layer in Pearl river delta estuaries

港珠澳大桥岛隧工程从满足香港、澳门和珠海三地勘察标准出发,需要建立一个符合英国标准(BS)和中国标准(GB)的工程地质单元层,为岩土工程评价提供基础依据。综合利用工可、初勘、详勘和补勘成果,根据地质成因及时代、地层岩性及物理力学性质,统一不同规范的资料,划分符合国内外勘察标准的工程地质单元层,为珠江三角洲入海口工程地质单元层确立提供基础。

Hong Kong-Zhuhai-Macao bridge island tunnel project needs to meet the investigation standards of Hong Kong, Macao and Chinese Mainland. Thus it＇s necessary to set up an engineering geological unit layer to provide the criterion for geotechnical engineering evaluation. Based on the feasibility stage investigation report, preliminary investigation report, detailed investigation and supplement investigation report, and according to the geological origin and times, soil information rocks and physical ＆ mechanical properties, we unify different specifications divide the engineering geological unit layer in keeping with investigation standards to provide a basis for the Pearl river delta estuaries.
