摘　　要：浙江大学科技园工程A楼长度为300 5m,通过加强桩基质量控制沉降,对地下室结构与上部结构采取加强钢筋、预应力技术、后浇带、变形缝、微膨胀混凝土等综合技术措施,对不同部位采取相应的措施,有效解决了超长结构的混凝土裂缝问题。The length of Building A of Science and Technology Park of Zhejiang University is 300.5 meters. Engineers adopted comprehensive technical measures, including improving pile foundation quality to control sedimentation, using enhancing steel bars in the basement structure and upper structures, prestress technology, post-pouring zone, deformation joint, micro-dilatancy concrete and so forth, took relevant measures according to different parts and effectively solved the concrete crack problem of ultra-long structures.
