| Executive Summary | The subsoil off-Sensyu in Osaka bay is composed of a soft alluvial layer and successive diluvial clayey deposits with sandy seams. The influence of overburden which arises from reclamation of sea area by the construction of Kansai International Airport, is expected to be transfered to the layers over several hundred meters deep. The appropriate soil investigation of the deep layers is required to provide the high quality of undisturbed samples. In the Port and Harbour Research Institute, the conventional wire-line sampling system mainly adopted for sampling soft rocks was improved so as to be able to apply the various types of soils. The improved PHRI type wire-line sampling system was used for the soil investigation performed in 1981 at the project site in Osaka bay. The details of the PHRI type wire-line sampling system and the records of application are presented in this paper for the reference of the soil survey in future at the port and harbour area. |
