A Study on Internal Force Monitoring and Back Analysis of Supporting and Protecting Structure of Rock Deep Foundation

Abstract:

With the rapid development of bridge engineering, the application of supporting and protecting structure that embeds in deep foundation engineering is gradually applied in the design and construction of large-scale suspension bridge. Due to the few amount of stress gauge steel that are pre-installed in the diaphragm wall reinforcement cage in deep foundation engineering and discrete data, it is difficult for the existing frequently-used method to reflect stresses of each part of the wall truly. And for major engineerings, like anchorage foundation, it is necessary to know the stress state of diaphragm wall on time in order to provide basis for decision making for the excavation site. By adopting finite element method, demonstrating the characteristics of its force reversely by using wall deformation and based on the wall deformation data measured in the field, this paper provides strong guarantee for ensuring the safety and reliability of construction.
