在这项研究中,建立了潮汐引起的孔压、渗流力和水流入水下排水隧道的解析解。计算结果与商业软件的数值解进行了比较。讨论了土体渗透性、剪切模数、衬砌厚度和埋深对潮汐孔压、渗流力和涌水量的影响。隧道埋深越小,土的渗透性越高,潮汐引起的孔压和渗透力越大。对不同深度处最大潮汐孔压的相位滞后进行了测定和研究。
In this study, analytical solutions for tide-induced pore pressure, seepage force and water inflow into a subaqueous drained tunnel are developed. The results are compared with numerical solutions from a commercial software. The effects of the soil permeability, shear modulus, lining thickness and buried depth of the tunnel on tide-induced pore pressure, seepage force and water inflow are discussed. Larger tide-induced pore pressure and seepage force are obtained for smaller tunnel depth and higher soil permeability. The phase lags of the maximal tide-induced pore pressure at different depths are determined and investigated.
