A kind of crack with similar characteristics has been discovered on the upstream surface of super-high arch dam. In this paper, the reason of cracking was analyzed by the three-dimensional finite element method. It is found that the stress concentration of concrete near the water-stop structure led to the concrete initial cracking in the process of transverse joint open.

Gallery cracks occur commonly in concrete dams, but their cracking mechanism has yet to be effectively revealed. In this paper, the actual temperature, stress change history and cracking process of a gallery area were uncovered, based on the safety monitoring data of cracks in a super-high arch dam. In addition, the basic development and change laws, as well as the corresponding cracking mechanism, were analyzed, and the real causes and influential factors of cracks at the site were revealed, which will provide a reference for the prevention of cracks in similar projects in the future.

The paper presents the design and static analysis of a high arch dam. A feasibility study was conducted on the dam in the 90s and a preliminary layout was designed. However, the dam’s construction phase has been never started. In this paper, the design and layout of the dam under consideration are in accordance with the US manuals for the design of arch dams. The structure’s three-dimensional model was entered into the program SAP2000 and three-dimensional solid finite elements were used to discretize the model. This paper considers the hydrostatic pressure of the water reservoir and concrete self-weight. The analysis was performed for both the maximum and the minimum designed water level and for the case when the reservoir is empty. Special attention is given to the boundary conditions of the dam at its abutments and foundation. The results show that the planned layout is good for the dam’s construction. The arch dam’s curve transfers the loads to the abutments. The significant role of the foundation rigidity and the reservoir water level in the stress distribution and nodal displacements within the arch dam is observed.

This study main focuses on a real-time Zigbee-based localization system to provide prompt support for safety management in dam construction sites. The system accounts for a wireless sensor tracking technology and a set of servers running software for handling collected data, real-time site state visualization and remote interaction communications with other system such as ERP, CRM. The low-level tracking technology is a ZigBee-based network hardware utilizing fingerprinting software technology. The proposed real-time monitoring system for employer has been successfully implemented in Xiluodu arch dam construction site. The field tests also show that the RSSI-based localization algorithm implemented by ZigBee devices is reliable and is accurate (3 to 5 meters) enough. This real-time monitoring system was proven to be very useful for field safety management of high arch dam, and in similar hydraulic projects.

Cracking Risk

It is of great significance to study the cracking risk, the overall stability, and the reinforcement measures of arch dams for ensuring long-term safety. In this study, the cracking types and factors of arch dams are summarized. By employing a nonlinear constitutive model relating to the yielding region, a fine three-dimensional finite element simulation of the Xulong arch dam is conducted. The results show that the dam cracking risk is localized around the outlets, the dam heel, and the left abutment. Five dam stress zones are proposed to analysis dam cracking state base of numerical results. It is recommended to use a shearing-resistance wall in the fault f57, replace the biotite enrichment zone with concrete and perform consolidation grouting or anchoring on the excavated exposed weak structural zone. Three safety factors of the Xulong arch dam are obtained, K_1 = 2~2.5; K_2 = 5; K_3 = 8.5, and the overall stability of the Xulong arch dam is guaranteed. This study demonstrates the significance of the cracking control of similar high arch dams.
