Abstract

The basic policy in Japan is to build nuclear reactor buildings on rock. But, in order to cope with the middle and long term siting problems it has become necessary to develop new siting technology from the standpoint of expanding the available range of site selections and effective utilization of lands. The gravelly soil layer in the Quaternary deposits has high possibility of becoming the bearing soil stratum when constructing a nuclear power plant. In order to verify the seismic stability of such gravelly soil layers, a series of field dynamic and static torsional loading tests for large scale in-situ soil columns were performed. In addition, a series of laboratory tests using a large scale triaxial test apparatus on high quality undisturbed gravel samples obtained by in-situ freezing method were performed. Herein reported are the sampling method of high quality undisturbed samples, laboratory test results and the large in-situ soil column test results.

Gravelly Soil Properties by Field and Laboratory Tests

St. Louis, Missouri

The basic policy in Japan is to build nuclear reactor buildings on rock. But, in order to cope with the middle and long term siting problems it has become necessary to develop new siting technology from the standpoint of expanding the available range of site selections and effective utilization of lands. The gravelly soil layer in the Quaternary deposits has high possibility of becoming the bearing soil stratum when constructing a nuclear power plant. In order to verify the seismic stability of such gravelly soil layers, a series of field dynamic and static torsional loading tests for large scale in-situ soil columns were performed. In addition, a series of laboratory tests using a large scale triaxial test apparatus on high quality undisturbed gravel samples obtained by in-situ freezing method were performed. Herein reported are the sampling method of high quality undisturbed samples, laboratory test results and the large in-situ soil column test results.
