摘要:为了解决袖阀管注浆开环压力难以确定的问题，基于厚壁圆筒理论模型，给出了任意倾斜状态下 袖阀管出浆口地层应力计算方法，结合第四强度准则，建立了可考虑多因素综合影响的袖阀管注浆开环压 力理论计算公式，并进行开环压力影响因素分析。结果表明：袖阀管注浆开环压力随套壳料抗压强度、套 壳料与土体泊松比比值、注浆深度、地层最小与最大水平主应力比值的增大而增大，随套壳料内外半径比、 套壳料与土体弹性模量比的增大而减小。套壳料抗压强度、套壳料内外半径比、注浆深度以及注浆钻孔方 向对开环压力的影响较其他因素显著。将本文建立的袖阀管注浆开环压力计算公式应用于新建大冶北至阳 新铁路DK107+105框架顶进涵工程，并与现有开环压力计算方法进行对比，结果表明，利用本文计算方 法计算的开环压力值更接近现场实测范围，并优于现有计算方法。研究结果可为袖阀管注浆理论发展及现 场应用提供支持。

Abstract:In order to solve the problem that it is difficult to determine the open-loop pressure of sleeve valve pipe grouting， Based on the theory model of casing and cement ring， the calculation method of formation stress at the outlet of sleeve valve pipe under arbitrary inclination was given. Combined with the fourth strength criterion， the theoretical calculation formula of open-loop pressure of sleeve valve pipe grouting was established， which can consider the comprehensive influence of multiple factors， and the influencing factors of open-loop pressure were analyzed. The results show that the open-loop pressure of sleeve valve pipe grouting increases with the increase of the compressive strength of casing material， the ratio of Poisson ratio of casing material to soil， the grouting depth， the ratio of minimum and maximum horizontal principal stress， but decreases with the increase of the inner and outer radius ratio of casing material and the ratio of elastic modulus of casing material to soil. The compressive strength of casing material， inner and outer radius ratio of casing material and grouting depth have more significant influence on the open-loop pressure than other factors. The direction of grouting hole has great influence on the open-loop pressure. When α is constant， the open-loop pressure decreases with the increase of β ，and when β is constant, the open-loop pressure increases with the increase of α. The formula for calculating open-loop pressure of sleeve valve pipe grouting is applied to the new construction of DK107+105 frame ejectionculvert project from north Daye to Yangxin Railway, and compared with the existing methods. The results showthat the open-loop pressure calculated by the method in this paper is closer to the field measurement range, and isbetter than the existing methods. The research results can provide support for the theory development and field application of sleeve valve pipe grouting.
