Abstract: According to different regions, conditions and requirements, the cross-fault measurement specifications is allowed to measure at different resurvey periods, and resulted in unequal interval observation data. The unequal interval observation data is a common phenomenon data, the difference on both sides of the fault is observed by geological investigation, historical record, artificial observation, simulated record, digital sampling, encrypted observation before and after the event, change of observation equipment, change of observation environment, human factors, etc, and the unequal interval observation data is obtained. The characteristics of the unequal interval observation data is not only shown in time, but also in space. The unequal interval observation data is usually preprocessed into equal interval data by some kind of algorithm chosen before the subsequent complex calculation. In the data processing of cross-fault measurement, the unequal interval observation data is usually preprocessed into equal interval data, and then calculated, which leads to a series of new problems, such as time calculation, synchronization, master-slave relationship, comparability and so on. In view of unequal interval observation data in cross-fault measurement, some new problems are tried to solve in unequal interval data matching calculation by using conventional methods combined with some algorithm requirements, data characteristics and practical experience, and their adaptability in various algorithms is investigated in this paper. These works contribute to the improvement and development of cross-fault survey data processing methods, and enhance the role of cross-fault survey data in earthquake protection and disaster reduction.

Abstract: China's hydropower has been developed rapidly, and cascade hydropower stations have been established in many basins. Once a dam fails, the induced flood could wreak havoc downstream and on both sides. Therefore in contemporary China, the safety and emergency management of hydropower engineering is very important. The main purpose of this paper is to provide reference for the sustainable and healthy development of China's hydropower station construction and management. Firstly, this paper summarizes the overall situation of China's hydropower engineering safety and emergency management from the perspective of related regulations and related authority responsibilities. Secondly, the current situation of safety and emergency management in three typical basins with different characteristics is investigated and studied. Finally, the main features of the safety and emergency management of hydropower engineering in China are analyzed and summarized. Based on these studies, it can be concluded that as a country with the largest installed capacity in the world, China has attached great importance to the safety and emergency management of hydropower projects and has formed a systematic management mechanism, which has three characteristics: (1) Comprehensive and detailed regulations and standards; (2) Broad responsibilities and significant roles of governments and their subordinate bodies; (3) Basin-based safety and emergency management.
