地连墙板桩码头结构耐久性分析

Analysis on Durability of Sheet-Pile Wharf Structure of Diaphragm Wall

唐山港京唐港区是较早采用地连墙板桩码头结构型式建设的港区,至今已经20余a。地连墙板桩码头结构耐久性问题一直是工程界关注的重点。根据工程实际,详细讨论水位变动区板桩墙混凝土的耐久性和钢拉杆的防腐蚀问题;介绍为增强水位变动区板桩墙抗冻耐久性和解决钢拉杆防腐蚀问题所采取的具体措施。

Jingtang Harbour Area of Tangshan Port is the area earlier adopting sheet-pile wharf structure of hragm hragm wall. The area up to now has been more than 20 year. The durability of sheet-pile wharf structure of wall has been the key point concerne concrete in the water level changing area d by the engineering circles. The problems of durability of sheet- and anti-corrosion of steel tie rod are discussed in detail. The measures to strengthen the durability anti-freeze of sheet-pile wall in the water level changing area and solving the anti-corrosion of steel tie rod are introduced.
