Construction technology on pile foundation of No. 6 main pier in Dashengguan Yangtze Bridge

Hongbin YU , Zeping LIAN ,

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 3,   Pages 339-343 doi: 10.1007/s11709-009-0047-9

Abstract: Based on pile foundation construction of No. 6 main pier, deep mudstone geological foundation and deep-water construction in Nanjing-Dashengguan Yangtze Bridge, the method of super-large-diameter bored pile in deep water is studied. The spread drill, application of PHP mud, and choice of machine are solved by adopting two machines of KTY4000 and KPG300A. Besides, the airlift reversing circulation is selected in slag discharge. The results show that this method can ensure successfully the construction of pier foundation to satisfy the demands of codes.

Study on shaft drilling and blasting construction risk analysis and countermeasures of Bohai Strait tunnel

Zhang Wenxin and Zou Chong

Strategic Study of CAE 2013, Volume 15, Issue 12,   Pages 101-106

Abstract:

In view of the shaft construction risk analysis of Bohai Strait tunnel, this paper determines risks during construction. Combining the risk weight analysis ranking,the sequence in turn from low to high is supporting structure failure risk, natural disaster risk and shaft excavation risk. Through risk assessment,we determine that the risk of water inrush and mud outburst is the key risk. Considering the influences of key risk and other risks on the shaft construction,we put forward response measures about shaft construction risk of Bohai Stiait tunnel from the geological forecast,shaft hoisting equipment selection and hoisting process control, shaft excavation risk control, natural disaster risk prevention, shaft supporting structure for quality control and the establishment of the shaft system construction,which provide guidance for the subsequent construction.
