英文摘要 | The underground complex of the Baihetan hydropower plant in Yunnan Pipvince, China, is currently the worlds largest underground on caverns under construction. The seismic stability of the underground complex is studied in this paper. A preliminaly performance-based seismic assessment approach specified for underground rock caverns is firstly proposed in this paper following the existing International Standard ISO23469: 2005. The performance objectives are classified based on the electricity generating function of the powerhouse as serviceability and safety. The reference earthquake motions are specified for each performance objective as Operating Basis Earthquake OBE), and Safety Evaluation Earthquake (SEE). The seisrnic variables of Baihetan project are determined for the OBE and SEE. And simulated wave forms for the dynamic analysis are conducted. Detailed dynamic response analysis (Method 2B) is conducted with both 2-D and 3-D elasto-plastic dynamic analyses, based on the parameter given by medium strain rate cycle loading dynamic tests. Acceleration, stress, displacement and failure zones are studied. And die seismicspectrum characteristicis analyzed with a newly introduced wavelet packet technique. The mechanism of the support. measure for seismic stability is also discussed. The assessment for seismic performance of Baihetan underground powerhouse complex is obtained by integrating these results. The serviceability objective of the underground powerhouse under OBE may be satisfied, and the safety objective is feasible but with the proposed support system. Seismic isolation design is preferred, yet not necessarily. And if any seismic isolation design is lobe adopted, the absorb range of the isolation material is expected to be 1 similar to 4 Hz. |
