摘要盾构隧道长期渗漏水严重影响着管片外侧水土荷载作用。通过理论分析获得隧顶上覆竖向平均渗透梯度表达式和考虑大主应力拱效应的侧向土压力系数计算公式，进一步构建考虑长期渗漏水效应的隧顶水土荷载计算模型，依托横琴隧道下穿马骝洲水道段两个典型断面的地质条件和水土荷载实测结果，对不同计算工况下的理论分析结果和现场实测值进行对比分析。得出以下主要结论：提出模型能够对海相段和陆相段的盾构隧道隧顶水土压力进行合理有效评价，相比Dimitrios Kolymbas有效应力法和Terzaghi总应力法，本文方法误差最小；随着土体内摩擦角增加，侧向土压力系数呈现先略减小后增大的变化规律，表明达到一定条件时土拱效应对侧向土压力系数才能起主导作用影响；隧顶水土荷载与隧道埋深直径比呈现增加速率逐渐衰减的正相关关系，与土体重度和管片外侧水头呈现线性正相关关系，与单宽渗漏水量呈现线性负相关关系。相关研究成果能够为我国水下盾构隧道合理设计提供理论依据。

Abstract：The long-term water leakage of shield tunnels seriously affects the water and soil loads on the outside of the segments. Through theoretical analysis，the expression of the vertical average permeability gradient over the tunnel roof and the calculation formula of the lateral earth pressure coefficient considering the arching effect of maximum principal stress were obtained，and the calculation model of the water and soil load on the top of the tunnels considering the effect of long-term water leakage was further constructed. Relying on the geological conditions of two typical sections of the Hengqin tunnel，the theoretical analysis results were compared with the field measurement results of the water and soil load under different calculation conditions. The following conclusions are that the model in this paper can reasonably and effectively evaluate the water and soil pressure on the top of shield tunnels in marine and land sections and has the smallest error compared with the Dimitrios Kolymbas effective stress method and the Terzaghi total stress method. With increasing the friction angle，the lateral earth pressure coefficient shows a slight decrease first and then increase trend，indicating that the soil arching effect can play a leading role in the lateral earth pressure coefficient when certain conditions are reached. The water and soil load on the top of the tunnel presents a non-linear positive correlation with the buried depth ratio of the tunnel，a linear positive correlation with the soil gravity and the water head outside the segment，while a linear negative correlation with the leakage of a single width. Related research results can provide theoretical basis for the rational design of underwater shield tunnels.
