摘要

对于水下隧道开挖后隧道围岩中渗流作用对隧道结构水荷载的影响问题，应用复变函数理论方法，建立了水下隧道加固区渗流模型，研究得出考虑加固区渗透率和加固区厚度参数影响的渗流解析解。研究表明，当围岩加固区渗透能力变小时加固区围岩中的水力梯度将增大，加固区半径增加，加固区内的水力梯度也有所增加，但加固区渗透率大小对水力梯度的影响较加固区范围大小变化的影响大很多。在围岩中渗透力的影响起主要作用；加固区在常规厚度范围内变化对围岩中水力梯度的影响相对很小，厚度只需满足相关要求即可。数值解证明了理论解的合理性。

Abstract

Based on the problem to water load acted on the tunnel structure because of seepage after excavating

this paper uses the theoretical method on complex variable function to establish the seepage model considering the reinforced area

and the study obtains the seepage analytical solution considering the influences of the permeability and thickness parameters of reinforced area. One hand

the research indicates that the hydraulic gradient of the reinforced area will be amplified when the seepage capacity weakens; on the other hand

the hydraulic gradient is also amplified when the reinforced area is increased

but the effect of seepage capacity on the hydraulic gradient is more significant than the reinforced area. So the effect of the permeability of reinforced area on the seepage force in the surrounding ground is the main cause

and the effect of the thickness of reinforced area is much slighter. It can be seen that the thickness is just satisfied with the relative requirements. The compare between analytical solutions and numerical solutions proves that the analytical solutions are rational.
