摘要

摘要: 盾构隧道掘进过程中推力是盾构施工安全的重要因素。为了能够准确地估算水位线以下盾构掘进过程中所需的推力,分析水浮力对盾构机的受力影响。推导水浮力影响下的盾构推力计算公式,基于现场实测数据分析盾构推力与扭矩之间的关系。研究结果表明推导的盾构推力计算公式可以与现场盾构推力吻合良好,推导的推力计算公式可以用于水位线以下盾构的推力计算；扭矩与盾构推力具有良好的线性关系,因此可以通过推力计算盾构扭矩。

Abstract: Thrust is an important factor in shield construction safety during shield tunneling. In order to accurately estimate the thrust required during shield tunneling below the water level, the influences of water buoyancy on the force of shield tunneling are analyzed. The formula for calculating the shield thrust under the influences of water buoyancy is derived, and the relationship between the shield thrust and the torque is analyzed based on field measured data. The research results show that the deduced formula for the shield thrust can be in good agreement with the on-site shield thrust, and it can be used to calculate the thrust of the shield below the water level. The torque has a good linear relationship with the shield thrust, so the shield torque can be calculated through the thrust.
