【摘要】：ATS水電站廠房尺寸較大,主機(jī)間長(zhǎng)87.6 m,寬43.3 m,水下部分高35 m。由于地形、地質(zhì)條件的制約,主機(jī)間基礎(chǔ)位于不同的地基介質(zhì)上,傳統(tǒng)的結(jié)構(gòu)力學(xué)方法計(jì)算地基應(yīng)力不能體現(xiàn)地基介質(zhì)不同對(duì)地基應(yīng)力的影響,需要采用三維有限元方法對(duì)其進(jìn)行模擬計(jì)算。根據(jù)地質(zhì)勘察、設(shè)計(jì)資料,建立三維有限元網(wǎng)格模型,模型模擬了廠房主體結(jié)構(gòu)以及主機(jī)間、尾水閘墩下部的地質(zhì)構(gòu)造,進(jìn)行無樁基及有樁基情況下的地基應(yīng)力和變形對(duì)比計(jì)算,論證在地質(zhì)條件不良情況下設(shè)置樁基的必要性。
[Abstract]:ATS hydropower plant has a larger size, 87.6 m between mainframes, 43.3 m in width, and 35 M. in the underwater part because of the terrain and geological conditions. The foundation between the main engine is located on the different foundation medium. The traditional structural mechanics method can not reflect the influence of the foundation stress on the ground medium, and the three-dimensional finite element method is needed. According to the geological investigation and the design of the data, the three-dimensional finite element mesh model is set up. The model simulates the main structure of the factory building and the geological structure of the bottom of the tail water gate pier, and carries out the calculation of the stress and deformation of the foundation under the condition of no pile foundation and the pile foundation. It is necessary to demonstrate the necessity of setting the pile foundation under the condition of bad geological condition. It's sex.
