【摘要】：在相似地質(zhì)條件下,與體量相似、荷載大小相近的常規(guī)基礎形式的高層建筑相比,大底盤高層建筑平均沉降量大幅減少;竣工后的后期沉降占總沉降量比例小,一般不超過20%;沉降穩(wěn)定時間短,通�？⒐ず�1年左右沉降即達到穩(wěn)定。當高層建筑撓曲值不超過0.2‰,且筏板的抗裂度大于或等于2時,高層下筏板可僅考慮局部彎矩作用,整體彎矩可通過構造措施處理;高層建筑撓曲值超過0.2‰,或筏板的抗裂度小于2時,筏板須考慮整體彎矩作用。
[Abstract]:Under similar geological conditions, the average settlement of tall buildings with large chassis is significantly reduced compared with high-rise buildings with similar body mass and similar loads. After completion, the proportion of settlement to the total settlement is small, generally not more than 20, and the settling time is short, and usually the settlement is stable about one year after completion. When the flexural value of high-rise building is not more than 0.2 鈥，
