In the light of the low - lying pile cap foundations designed for main piers no. 2 and no. 3 of tianluo bridge on wenzhou - fuzhou railway. this paper describes the ways to resolve the construction problems of the foundations in deep water in sea and at seabed that is steep and without overburden, using the construction techniques of underwater rock blasting, steel cofferdam floating, positioning, bottom sealing and manual pile digging
摘要針對溫福鐵路田螺大橋2號、 3號主墩設計上採用低樁承臺基礎情況，介紹運用水下巖石爆破，浮運鋼圍堰就位、封底、人工挖孔樁等施工技術解決海上深水、河床陡峭且無覆蓋層的基礎施工難題。 -
Based on the idea of the measured displacement can be divided into elastic and plastic parts, elastic parameters can back analyzed by the elastic displacement, which is the measured instant after blasting excavation. the strength parameter can be got by plastic deformation, which is the measured during the period of construction loop without blasting excavation. lastly, depending on fenner formula, a new and valid evaluating criterion for tunnel stability is presented and the effect of deformation modulus, cohesion, internal friction angle and overburden can be considered
