重庆鲁祖庙历史文化街区道路改建方案研究与实践

Research and Practice on Road Reconstruction of Luzu Temple Historical and Cultural Block in Chongqing

摘要:

随着城市更新进程的推进，城市核心区道路改造面临交通强度高、重载车辆多以及历史文化保护等多重挑战。以重庆市渝中区鲁祖庙历史文化街区道路改造项目为例，系统分析了石材路面破损的主要类型及成因，并提出综合性整改方案。研究发现，路面破损主要由施工养护期不足、交通荷载集中、基层材料强度差异及环境因素共同导致。通过优化路面结构设计、加强基层处理、增设混凝土反坎及更换防沉降井盖等措施，显著提升了道路耐久性与功能性。研究成果为城市核心区历史文化街区的道路更新改造提供了技术参考与实践经验，对平衡交通需求与历史风貌保护具有借鉴意义。

Abstract:

With the advancement of urban renewal, the road reconstruction in urban core areas faces multiple challenges, including high traffic intensity, heavy-duty vehicle loads, and the preservation of historical and cultural heritage. Taking the road reconstruction project of the Luzu Temple Historical and Cultural Block in Yuzhong District, Chongqing as an example, the main types and causes of stone pavement damage are systematically analyzed, and the comprehensive rectification schemes are proposed. The research reveals that the pavement damage is mainly caused by insufficient construction curing period, concentrated traffic load, strength differences of base materials and environmental factors. By optimizing the pavement structural design, strengthening the base layer treatment, adding the concrete counterforts and replacing the anti-settlement manhole covers, the durability and functionality of the road are significantly improved. The study result provides the technical references and practical insights for road renewal and reconstruction in historical blocks within urban core areas, which has reference significance for balancing the traffic demand and the protection of historical features.
