STATISTICAL ANALYSIS OF FAULTS OR FAILURE FOR RATIONALIZATION OF INSPECTION OR PATROL FOR RIVER LEVEES

Abstract

Inspection or patrol plays an important role in the condition monitoring of river levees in Japan. The analysis of data obtained in the inspection or the patrol was attempted for the rationalization under the human resource shortage or the financial limitation.

The results depicted the relation between the faults, the failure and the characteristic of river levees. There is correlation between the piping and the hydraulic gradient or soil stratum of river levees and its foundation ground. However, no correlation was found between that faults and the characteristic. The results suggest that the priority section for the inspection or the patrol could be specified by the characteristic of river levee with the failure history.
