Abstract
This study was conducted with the aim of applying three dimensional Boundary Element Method in analysis of ground excavation. The methods studied were dead load analysis for evaluating initial ground pressure and stage excavation analysis which permits consideration of construction schedule. And a tunnel intersection problem and a shaft excavation problem were analysed using these methods.
Following results were obtained.
(1) By supplying dead load analysis method, it is possible to obtain three dimensional initial ground pressure accurately.
(2) Accurate analysis of three dimensional stage excavation is possible with Boundary Element Method.
(3) These methods can be applied to practical problems for three dimensional underground excavation.
