摘要
鉴于国内目前气泡剂技术在辅助土压平衡式盾构施工中存在的一些问题 ,本文在考虑气泡剂技术在土压平衡式盾构施工中的功效基础上 ,从气泡剂自身性质和气泡混和土力学性质两方面着手 ,结合土压平衡式盾构施工的原理 ,阐述了气泡剂在盾构掘进施工中应用效果评价的手段及相应的指标 。
The foam agent is used to regulate the soil condition during earth pressure balance (EPB) shield excavating, how to estimate the effect of the foam agent technique is very important and there are still some unknowns. Based on studying the tunnel boring method and property of foamed soil, some methods and judgment criteria for evaluation of the properties and effectiveness of the foam are discussed and some suggestions are given for its application and selection.
