[摘要]地質(zhì)科學(xué)院科研實驗樓具有上部結(jié)構(gòu)偏置,荷載不均勻,基礎(chǔ)差異沉降量大,水浮力較大、樓板開大洞、穿層柱等主要特點。通過對主樓區(qū)域采用CFG樁復(fù)合地基解決建筑物不均勻沉降的問題;通過增加壓重,并適當(dāng)下移基礎(chǔ)底標(biāo)高的方法解決結(jié)構(gòu)整體抗浮問題;針對結(jié)構(gòu)不規(guī)則的情況,通過大量的計算分析,以及嚴(yán)格的抗震措施,確保了結(jié)構(gòu)在地震作用下具有良好的抗震性能。

Abstract: Leaning upper structure, uneven distribution of load, large differential settlement of the foundation, great water buoyancy, big holes in upper floors and cross-pillar are main characteristics of the research and laboratory building of the Academy of Geological Sciences. To solve the problem of differential settlement of buildings by using CFG pile composite foundation in the main building area. By increasing the self-weight and moving down the foundation of the structure to solve the problem of the whole resistance to float. A large number of structure analysis as well as better seismic resistance measures were taken into consideration due to structural irregularity which ensured that the structure has good seismic performance under earthquake. Seismic performance is ensured through lots of calculation and strict aseismatic measures.
Keywords: CFG (cementflyashgravel) pile composite foundation; antifloating design; differential settlement; structural irregularity items; construction measures
