The applicability of existing rock cover criteria for concrete lining pressure tunnels has bee reviewed in this paper and limitations placed based on site geology and any other site specific characteristics. Because the geological factors may occur great difficulties in operating pressure tunnels, it was necessary to fully recognize this factors at tunnel design and construction stages.

The object of this study is to establish a leakage safety management method for Juam Dam, a central cored rockfill dam in Korea, after appreciating the behavoral characteristics of the leakage monitoring data. In the water leakage monitoring of fill dam, the generation of abnormal water leakage is difficult to directly detect due to the effect of outside factors such as the component of precipitation inherent in the observation value. Therefore, conventionally estimation methods of water leakage quantity are applied by multiple regression analysis considering reservoir water level, precipitation, etc.. However, the estimated error of precipitation component is relatively big in these method. This paper identifies the water leakage quantity estimation formula linked to reservoir water level which is not directly affected by precipitation through the hydrograph separation analysis, and proposes a leakage management method.

Structural health monitoring(SHM) and damage identification are assuming larger and larger importance in civil engineering, SHM is defined as the use of in-situ, non-destructive sensing and analysis of structural characteristics in order to identify if a damage has occurred, define its location and estimate its severity, evaluate its consequences on the residual life of the structure. This paper studied the safety management network system of infrastructure which constructed smart sensors, closed- circuit television(CCTV) and monitoring system. This safety management of infrastructure applied to bridge, cut slop and tunnel, embankment and playground etc. It was constructed safety management system of various infrastructure to improve efficient management and operation for many infrastructure.

Recently, there are few cases of the Precise Inspection for Safety and Diagnosis for transverse crack of CFRD. The presumable causes and characteristics of transverse cracks have suggested in this paper based on field survey and related NDT. Also, the maintenance of transverse crack of CFRD are proposed.

According to this research, it was confirmed that safety coefficient is useful tool to rationally quantify structural deterioration of pipe. In addition, it could perform simple and rapid evaluation escaping from confinement by time and budget, and it can be utilized as a tool to set up policy for future water supply.
