Random finite element analysis on ground subsidence caused by tunnel excavation in karst regions with spatial variable soil

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...

Tunneling through soft clay

open access: yes, 2005
A new railway line was under construction in Northern Sweden, along the shoreline of the Gulf of Bothnia, between Umea and Ornskoldsvik. The ground conditions varied dramatically: Postglacial clay and silt valleys with intermediate ridges of crystalline, Precambrian bedrock, crossing the railway line.

Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.

CONSTRUCTION OF AN AIRPORT ON SOFT CLAY

open access: yesDoboku Gakkai Ronbunshu, 1989
A new airport is under construction off the coast of the present Tokyo International airport to cope with the increase in passengers and to reduce the noise problem. The construction site is located on the place which has recently reclaimed by soft clay with high water content.The paper describes the settlement of the ground treated by band drain, the ...
