Abstract
Concrete arch dam exhibits remarkable spatial-time characteristics because its working state might be evolved dramatically attributable to the dynamic construction process and operation environment. To overcome the limitations of routine design and analysis approaches for the high arch dam due to predetermined modes and assumptions, further advanced study is demanded to demonstrate the adequacy of structural analysis theories and calibration standards, as well as to evaluate its safety credibly. In this chapter, the systematic study on Xiaowan Arch Dam at a height of 294.5 m is exhibited, which covers the whole process from the back analysis of in situ geo-stress to the excavation/reinforcement of abutment/foundation, followed with the concrete placement/cooling/grouting operation until the reservoir impoundment/service. This study is supported by a toolkit termed as the “Digitized System of Xiaowan Arch Dam” (DSXAD) which is the combination of the instrumentation system, the FEM system towards the fields of permeability/temperature/deformation, and the decision making system towards engineering judgment. The evolution of the real working state of the arch dam has been thoroughly revealed, and a series of difficult technical issues such as the foundation rock EDZ and dam concrete cracks emerged during its construction, are successfully solved under the guidance of the DSXAD.
