Abstract
In the Wards District of Tokyo Metropolis, the depth of underground to construct public facilities such as subways, waterworks and sewers has been deeper and deeper for lack of open spaces on ground surface. The information of geology and soil character underlying the Districts, however, was not available for developing those deeper layers. Then Tokyo Metropolitan Government made the investigation of subsurface geology and its soil character in this District from 1989 to 1995. Fifty-four wells which depth are from 86m to 1, 000m were drilled for the purpose of the investigation throughout the District and neighborhood. It was cleared that mechanical properties of cohesive soil distributed nearly same horizontal levels were regionally grouped by analyses of soil test on drilled cores. This paper deals with the relationship between the regional distribution of those mechanical properties of cohesive soil and past eroded thickness estimated from over consolidation ratio.
