［摘要］主要探討了泄水減壓法在地下室抗浮設(shè)計中的原理，研究了泄水減壓技術(shù)在實際工程中的適用范圍和主要特點。通過采用FLAC3D軟件對五角西岸住宅項目的地下室進行抗浮分析，揭示了地下室側(cè)面泄水孔間距大小對泄水減壓效果的影響規(guī)律。通過模擬分析，探討了地下室表層回填土夯實程度對泄水減壓效果的影響。結(jié)果表明，表層回填土夯實與否是地下室抗浮安全的關(guān)鍵因素。最后，針對地下室側(cè)面泄水孔布置情況開展多參數(shù)、多工況抗浮設(shè)計計算，提出了泄水孔的合理間距范圍及有關(guān)地下室設(shè)計施工的建議。

"Abstract:The principle of water-discharging pressure relief method application in the anti-floating design of basement was mainly discussed. The application scope and main characteristics of the water-discharging pressure relief technology in practical engineering were studied. Through applying FLAC3D software in anti-floating analysis of the basement for Wujiaoxi′an Residential project, it reveals that the influencing laws of the spacing of drainage holes in basement on water-discharging pressure relief effect. The influence of compaction degree of surface backfill soil for basement on water-discharging pressure relief effect was discussed through simulation analysis. Results show that the compaction degree of surface backfill soil for basement is an critical factor for anti-floating design of the basement. Finally, anti-floating design calculations with multiple parameters and multiple working conditions were carried out for the arrangement of the drain holes at basement sides, and the optimal spacing between drainage holes was suggested along with advices on the design and construction of basement."
Keywords:basement; water-discharging pressure relief technology; drain hole; numerical simulation; backfill soil
