Characteristics of consolidation settlements and sedimentary environments of the late Pleistocene-Holocene deposits in the Mekong Delta and Ho Chi Minh City, Vietnam

摘要

The report displays the characteristics of sedimentary environments, consolidation and consolidation settlements of the late Pleistocene-Holocene deposits in the Mekong Delta (MD) and Ho Chi Minh City (HCMC), Vietnam. The report furthermore discusses the influences of sedimentary environments on the consolidation properties and the resulting complex and large consolidation settlements. They cause land subsidence and uneven settlements of foundations in HCMC and the MD. They have especially combined with the unsuitable plans, land use like land fill in the lower land, rivers and ponds in the delta and increase in sea level by the global climatic change. As a result, it is very difficult to improve waterlogged areas in HCMC and the MD by the rain and tide waters. It is also not easy to propose a standard strategy for the management, planning and construction of these areas.
