河北工业大学工程硕士学位论文强夯法处理红层泥岩在济邵高速公路路基填筑中的应用研究摘 要随着我国经济的发展，公路建设也不断向山区延伸。由于山区地质地貌情况复杂，自然条件差，生态环境脆弱，给工程建设带来了较大困难。一方面高填深挖多，路基良性土填料缺乏，工程质量控制难；另一方面，路堑开挖产生大量废弃石方，恶化当地自然环境，诱发地质灾害。因此，就地取材的碎石土作为路堤填料越来越普遍。本文将结合济邵高速公路建设的实际，研究泥岩和泥质砂岩作为路基填料的适用性和可操作性。通过对济邵高速公路沿线泥岩和泥质砂岩填料的大量的室内试验，系统地研究泥岩和泥质砂岩填料的物理力学特性，分析其作为路堤填料的适用性；通过对强夯法加固路基机理的理论分析和现场检测试验，探讨不同的夯击能量和路堤施工的虚铺厚度对强夯的有效加固范围的影响，提出利用强夯进行施工的技术方案，并编制相应的施工工艺和质量控制标准；采用地质雷达、瑞利波、动力触探和固体体积率检测技术以及地质勘探方法等手段，针对泥岩和泥质砂岩作为路堤填筑材料，提出强夯施工工艺的质量检测方法和评价标准。综合分析和实际应用表明，强夯法处理泥岩和泥质砂岩填筑路堤可以达到要求的密实程度，且强夯方案优于碾压方案。关键词：强夯，处理，红泥岩，填筑，力学特性，实验研究，监测分析THE APPLICATION AND RESEARCH OF USING THE DYNAMIC CONSOLIDATION DEALING WITH THE RED MUDSTONE FILLING THE ROAD EMBANDMENT IN JISHAO EXPRESSWAY ABSTRACTWith the development of our national economy, highway construction has been extended to the mountainous district. As mountains complex geological features, poor natural conditions, fragile ecological environment, the project becomes more difficult. On the one hand, the project always has to high-filled or dig down into the soil, healthy filling is scanty, and quality control is difficult. On the other hand, cutting brings a large number of abandoned rock, then the local natural environment becomes worsen, and induces geological disasters. Therefore, getting the soil near the project as the road embankments filling becmomes increasingly commonplace.This paper will research the applicability and feasibility if they use mudstone and muddy sandstone as the road embankments filling according to the Jishao Expressway Construction. By the interior experiment about the mudstone and muddy sandstone next to Jishao highway , this paper will study the physical and mechanical properties of the mudstone and sandstone, and analyse the applicability of the embankment filling; Through the theoretical analysis and field testing of the dynamic tamping method, this paper will discuss the influence of the tamping energy and embankment thickness, then raise technology programmes and workout the corresponding construction technology and quality control standards; Using ground penetrating radar, Rayleigh wave, the dynamic penetration rate, solid volume detection technology and geological exploration methods, this paper will raise quality testing methods and evaluation criteria of the dynamic tamping metod which use mudstone and muddy sandstone as the road embankments filling.Comprehensive analysis and practical application shows that using the dynamic tamping method deal with the mudstone and sandstone filling embankment can meet the required level of the dense and the dynamic tamping programme is better than the rolling programme.Key words：dynamic tamping，dealing with，red mudstone，filling，experiment and research，check and analysis目 录第一章 11-1 课题的工程背景及意义11-2 国内外研究概况11-2-1 泥岩的物理力学性质研究11-2-2 强夯的加固机理及其工程应用21-3 本课题的主要研究内容61-4 技术方法和路线6第二章 泥岩和泥质砂岩填料物理力学特性的试验研究72-1 泥岩和泥质砂岩的成分及微观结构分析72-1-1 物理化学成分72-1-2 矿物成分及微观结构分析82-2 泥岩和泥质砂岩填料的工程特征92-2-1 颗粒级配对泥岩和泥质砂岩填料工程特性的影响92-2-2 击实试验92-2-3 泥岩和泥质砂岩填料的无侧限抗压强度102-2-4 泥岩和泥质砂岩填料的压缩试验112-2-5 泥岩和泥质砂岩填料的直接剪切强度122-3 小结14第三章 强夯施工质量的检测评价分析153-1 强夯加固机理153-1-1 概述153-1-2 地基的强夯加固机理173-2 瑞利波检测方法及应用193-2-1 瑞利波检测方法的基本原理193-2-2 瑞利波测试方法243-2-3 3.2.3 检测结果分析263-3 雷达探测方法及应用373-3-1 雷达探测方法的基本原理373-3-2 工作方法及步骤383-3-3 检测结果及分析423-4 重型动力触探试验463-4-1 触探的基本原理463-4-2 试验结果及分析473-5 本章小结48第四章 泥岩和泥质砂岩填筑路堤施工工艺494-1 填筑工艺方案的制定494-1-1 早期方案494-1-2 调整方案494-2 填筑方案的实施504-2-1
