复杂环境条件下市政河道整治工程设计方案研究

Research on Design Scheme of Municipal River Regulation Project under Complex Environmental Conditions

摘要:

市政河道作为城市主要过水通道起到盛蓄水体的作用，是防洪排涝的重要行泄通道。周边环境条件制约了河道整治工程的实施，也因此影响设计方案的选择。以浙江省嘉兴市车站港河道整治工程为例，由于周边存在既有建筑物，对整治工程实施过程中的边坡、挡墙位移和周边土体沉降有严格控制要求，因此在设计过程中提出了宽底板挡墙设计方案和边坡加固措施，并结合施工步骤进行了有限元模拟计算。证明了设计方案的合理性，为复杂环境条件下市政河道整治工程的设计提供参考和借鉴。

Abstract:

The municipal rivers， as main water crossing channels in cities， play the role of holding water and are the important channels of flood control and waterlogging drainage. The surrounding environmental conditions restrict the implementation of river regulation projects， and also impact the selection of design schemes. Taking the Zhejiang Province Jiaxing City Chezhan Port River Regulation Project as an example， and due to the presence of existing buildings around， there are strict control requirements for the side slope， retaining wall displacement and surrounding soil settlement during the implementation of the regulation project. Therefore， the wide-base retaining wall design scheme and the side slope reinforcement measures are proposed in the design process. And combined with the construction steps， the finite element simulation calculation is carried out to certify the rationality of the design scheme， which provides the valuable insights and references for the design of municipal river regulation projects under the complex environmental conditions.
