Abstract

Ueno underground station of the Shinkansen is a large scale underground station constructed in relatively stable diluvial layers. The construction was conducted with elaborated comparative designing, and with carefully controlled measurements referring estimated values, because data about design and construction of this kind of large underground station are rare. Primary estimations are qualitatively in good agreement with actual measured values, while quantitatively they do not agree well with the actual values. But the accuracy of the method of estimation will be increased in the future when more data about earth pressure of stable grounds are accumulated. Behavior of a diaphragm underground wall as a temporary structure, changes in groundwater level and displacement of the bottom of excavation are described in this paper.

Behavior of Braced Cut in Connection with Construction of Large Underground Station

St. Louis, Missouri

Ueno underground station of the Shinkansen is a large scale underground station constructed in relatively stable diluvial layers. The construction was conducted with elaborated comparative designing, and with carefully controlled measurements referring estimated values, because data about design and construction of this kind of large underground station are rare. Primary estimations are qualitatively in good agreement with actual measured values, while quantitatively they do not agree well with the actual values. But the accuracy of the method of estimation will be increased in the future when more data about earth pressure of stable grounds are accumulated. Behavior of a diaphragm underground wall as a temporary structure, changes in groundwater level and displacement of the bottom of excavation are described in this paper.
