【摘要】 交通道路工程作为水利水电枢纽的基础工程，在其建设和运行期都起着十分重要的作用。目前水电枢纽的道路工程几乎都是毫无疑问地采用一般交通道路工程的建筑材料、设计方法和施工技术。但由于水电枢纽工程道路的建设和运行环境都十分恶劣，车种复杂且载重量特大，要求道路的建设标准特别高，投资大，即使是一部分临时道路工程也只能如此。否则直接采用开挖暴露路面或泥沙石路面，维修困难、费用高且环境差、车辆损耗大。特别是道路工程建设枢纽的准备期，砂石系统尚未建立，需大量外运砂石，材料及运输费用高。而另一方面，枢纽的其他准备工程，如导流洞、交通洞等开挖的大量石渣又必须运走，没有得到有效利用且增加环境保护投资。这就在设计、选材等方面提出了一个新的问题，能否充分利用这些废弃石渣，又能适应这种恶劣环境，保障安全运用，还能降低生产成本的新型道路。 武汉大学、武汉路德材料有限责任公司，研制了一种新型无机胶凝材料，高强高耐水土体固结剂(High Strength and Water Stability Earth Consolidator，以下简写为HEC)，能良好地固结石渣、沙砾石和土体。这就为建设这种机关报型道路提供了物质基础。因此，本文结合水电枢纽工程特点，进行HEC混凝土道路工程设计和施工技术研究是具有重要的理论定义和实用价值的。 首先对国内外交通道路路面工程设计和施工技术进行了较广泛的调查分析，特别是对水电枢纽道路工程的特点，建设中的经济技术问题进行了分析，提出了适于水电枢纽道路工程建设的对策。 在总结交通道路工程设计理论的基础上，结合HEC混凝土的技术特点和水电枢纽工程道路的建设特点，提出HEC混凝土路面工程的设计方法、配合比设计公式及方法、弹性模量和抗折强度取值范围，将石渣粒径放宽至80mm，含泥量放宽至8％。 同时，在总结国内外道路工程施工技术的基础上，研究了适于HEC混凝土道路工程的施工技术，提出了配套的施工工艺、质量控制和验收办法，检测技术与标准，特别是提出了适于HEC混凝土的切缝时间与强度的关系和早期养护控制等。 结合瀑布沟水电站JC、JL段道路工程，进行了HEC-RCCP型道路工程试验。中文摘要对HEC一RCCP型道路工程的设计理论、方法和施工技术与工艺等进行了全面的实验和检验，该道路工程的质量检测结果充分说明了其合理性和实用性，同时总结提出了今后类似工程施工中应注意的问题。 结合田湾河水电站进场道路工程，进行了现浇HEC混凝土道路工程的试验和30.67km的推广施工。经业务和监理单位的工程验收，3个标段的30.67km道路全为优质工程，质量达到预期目标，进一步证明了设计理论、方法和施工技术的合理可行性。 最后进行了综合总结分析，阐述了HEC混凝土道路工程的技术经济优势和提前通车，便于施工的特点，建议迅速在水电枢纽工程和地方交通道路工程中推广应用。更多还原

【Abstract】 As a foundation engineering of hydroelectric key project, road engineering takes a quietly important role in its construction and operation. At present, road in hydroelectric key project almost adopts the construction material design method and construction technology of general road. Because of bad environment of operation and construction, varies vehicles and heavy load, it requires large investment and high level standard, even if it is temporary road. Otherwise, it would result in difficulty in maintenance and high expense and serious loss of vehicles if excavated and exposed the road surface or adopted mud and sand road surface. Especially during preparing phrase of the engineering, sand and stone system is not built, which require a large quantity of sand and stone from outside, which lead to high expenses of materials and transportation. On the other hand, rock ballast from other preparing engineering of the hydroelectric key project such as diversion tunnels, traffic tunnels and so on, must be transported off, which aren’t made good use of and add up investment of environment protection. It springs up a new problem that if there is a new road which can make use of the ballast compatible with the bad environment and ensure safe operation, even reduce the construction cost.Wuhan University and Wuhan Road Materials Ltd invent a new type of inorganic glue consolidator, so-called High Strength and Water Stability Earth Consolidator, dubbed HEC, can solidify the ballast, sand gravel and soil, which supports material base for this kind of road. Therefore, this paper is o f s ignificance and p ractical value o n H EC c oncrete r oad e ngineering design and construction technigue research connecting with the characteristics of hydroelectric key project.Firstly, this paper raises appropriate strategy for waterfront electricalpivot road engineering construction, thorough comparing foreign and native road surface engineering design and construction technology exclusively, especially analyzing the economic problem in construction, according to the characteristics of hydroelectric key project.This paper points out HEC concrete road engineering design, mixture ratio design formula and method, elastic module and anti-mold strength extent, extend the grain size to 80mm, mud content to 8%, basing on summarizing road engineering design and HEC cement’s technology characters.Meanwhile, basing on summarizing road engineering design, the author works out construction technology t, quality control method, acceptance technology and inspection criterion suitable for HEC cement, specially gives the relationship of slice time to strength and early curing control.The author carried on HEC-RCCP road engineering experiments on Pubugou hydropower station in JC, JL road section and comprehensively practiced and inspected design theory, method and construction technology of the HEC-RCCP road engineering. The inspecting results of the section of road sufficiently show rationality and practicability, and at the same time the author summarized some attentive problems in analogical engineering.The author completed the field casting experiments of HEC concrete road and spread construction technique of 30.67km on Tianwan hydropower station input road. By acceptance of owner and supervisor, three section of 30.67km road are all excellent and the quality amounts to expectant aims, which proves the design theory, method and construction technology is reasonable and feasible.In the end the author summarizes and analyzes synthetically and illustrates the advances of technology and economic of the HEC concrete road engineering and the characteristics of convenient to construction andvehicles can be operated ahead. Demonstrate that HEC has economic advantages and operate ahead of time; finally, it is suggested to spread this technology rapidly in hydropower station and local road engineering.更多还原
