在压气沉箱下沉之前,在沉箱上设置多种应力应变计,纪录在下沉过程中变化情况。本文着眼于作用在沉箱上的外力,对设计值与现场计测值进行对比分析,为今后的设计施工提供真实的参考数据,提高设计施工的可靠性。 Before the pressure caisson subsidence, a variety of stress strain gauges were set on the caisson to record changes during the subsidence. In this paper, we focus on the external forces acting on the caissons, and compare the design values ​​with on-site measurements to provide real reference data for future design and construction, and to improve the reliability of design and construction.
