摘　　要：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 settlement of pneumatic caisson, many kinds of stressstrain gauges were installed on caisson and the surrounding foundation to record the variation during settlement. In terms of the external force on the caisson, the designed value and site measurement value were compared and analyzed to provide true reference data for future design and construction and to improve the reliability of the design and construction.

关 键 词：压气沉箱 现场计测 作用外力 对比分析 主动预测
