Abstract
Recently, even slopes are being built upon as never before. In such cases, designers need to take special measures to cope with the special conditions of slopes. However, there is no systematized database to help designers formulate such measures. Therefore, the Architectural Institute of Japan set up a working group to collect and analyze data from existing literature and summarize the latest technical information. This paper (Part 1) reports on the results of the analysis conducted by the working group and makes some proposals relating to the vertical bearing capacity of shallow foundations in and on slopes.
