[关键询]预应力抗浮锚杆：抗拔承载力：防水：施工工艺 [中分类]TU753.1 [献标识弱]A [章编]10028498(2010)09-0075-03 Improved Construction Technology of Prestressed Anti-floating Anchor in Some Project Li Qidong Zheng Wei Jiang Xiaofang Yao Yongquan Weihai Construction Group Co.Lad.Weihai Shandong 264200 China) Abstract:Raft foundation is designed in Weihai Public Cultural Center.The project locates in coastal area therefore prestressed anti-floating anchors are designed to prevent too large buoyancy caused by underground water.A new set of construction technology for prestressed anti-floating anchors is introduced from construction process improving multi profession cooperation and whole process control in order to solve associated difficulties of improving bearing capacity of prestressed anti-floating anchors and ensuring waterproof quality of joints.It proves that the new construction technology ean ensure anti- pulling capacity of prestressed anti-floating anchors and waterproofing effects of joints. Key words:prestressed anti-floating anchor:anti-pulling capacity:waterproof:construction process 目前工程中广泛应用的抗浮技术有抗拔裤和抗拔钢网架结梅，外墙多为破端暴墙，局部为干挂石材，为威 摇杆两种，其中抗拔的抗拔承载力较高，但成本也较海市标志性建筑.地下宣设有交物含等重要场所，防 高：抗拔错杆承载力相对低一些，成本也低得多，但其 水等级为I级，采用4mm厚聚氨酯防水涂料.由于工程 施工技术并不是很成熟.本交研究在不大幅度增加成 邻近海边，地下水位...
