摘要

为解决超长距离大断面岩石顶管项目中的卡管和顶力突增问题,本文通过直剪试验系统研究了不同碎屑粒径级配及不同碎屑与泥浆质量混合比下的管—岩复杂摩擦特性。结果表明:当碎屑总质量少且大粒径占比为主时,碎屑在接触面上形成犁沟效应,摩擦系数主要受接触面粗糙度控制;当碎屑总质量多且细粒径占比为主时,碎屑之间相互咬合,摩擦系数主要受空隙率控制。基于试验结果,利用改进后的顶力预测模型对现场顶力进行了反演分析,最终通过现场监测结果确认了本研究的正确性。碎屑的存在对顶进非常不利,后期形成的“饼化膨润土”条件导致摩擦阻力激增。因此,现场应及时清理管外碎屑,并考虑定期持续注入粘度较低的膨润土泥浆。研究成果可为解决该领域的问题提供新的研究思路和方法。

Abstract

To address the issues of pipe stuck and sudden increase in jacking force in ultra-long-distance and large-cross-section rock pipe jacking projects, this paper systematically investigates the complex friction characteristics between pipelines and rocks under different rock debris gradations and different mixing ratios of rock debris to slurry using direct shear tests. The results show that: When the total mass of debris is low and the proportion of large particles is dominant, the debris creates a furrow effect on the contact surface, with the friction coefficient primarily controlled by the roughness of the contact surface. Conversely, when the total mass of debris is high and the proportion of fine particles is dominant, the debris interlocks with each other, and the friction coefficient is mainly controlled by the void ratio. Then, an inverse analysis of the jacking force in the field based on the test results was carried out using the improved jacking force prediction model. The validity of this study was eventually confirmed by the results of the field monitoring. The presence of rock debris is very detrimental to jacking, and the inevitable formation of “cake bentonite” conditions at a later stage leads to a sharp increase in frictional resistance. Accordingly, the site should be cleared of debris from outside the pipe strings in a timely manner and consider regular and continuous injection of lower viscosity bentonite slurry. The study results can provide new research ideas and methods for solving problems in this field.
