大型围海工程中的堤身稳定性系统优化技术研究
发布时间：2018-08-16 13:08
【摘要】：软基筑堤的大型围海工程在设计和施工方面存在三个问题：1）缺乏系统、合理的技术来优化围堤断面，降低工程造价；2）设计和施工缺乏联动和协调；3）施工中缺乏系统的堤身稳定控制技术来控制堤身稳定。针对以上问题，本文提出了系统堤身稳定技术，主要包含设计和施工两个方面：1）从设计角度提出系统堤身稳定分析方法；2）从施工角度提出系统堤身稳定控制方法。 提出通过设计和施工联动，利用工程中的堤身稳定的各影响因素，将工程总体的施工进度安排和堤身稳定分析有机结合，实现总体最优的工程实施方案。该方法需要设计方和施工方共同参与设计方案和施工组织方案的确定，，能够充分发挥技术和工程实践的优势，达到降低工程造价的目的。同时该方法充分发挥设计和施工的联动性和协调性，对整个工程实施顺序的协调、衔接进行全局性把握，对每段围堤的施工要点和关键进行重点控制，充分体现了设计方案和施工组织的紧密协调和统一，对于控制工程质量和降低工程风险具有重要意义。 系统堤身稳定控制方法从施工速率、施工工序、龙口合拢、堤身监测和堤身险情控制等方面提出了合理、可行的控制方法。系统堤身稳定控制方法为软基围堤的施工组织和施工质量控制提供了理论支撑和指导方法，有助于施工方在施工过程有效控制堤身稳定，从而减少堤身变形带来的工程损失。
[Abstract]:There are three problems in the design and construction of the large reclamation project of soft foundation embankment: 1) lack of system, reasonable technology to optimize the section of embankment, and 2) lack of linkage and coordination between design and construction; 3) lack of systematic levee stability control technology to control embankment stability. Aiming at the above problems, this paper puts forward the system embankment stabilization technology, which mainly includes design and construction aspects: 1) from the design point of view, puts forward the system levee stability analysis method 2) puts forward the system dike stability control method from the construction point of view. It is put forward that the overall construction schedule arrangement and dike stability analysis can be combined organically through the linkage of design and construction, and the overall optimal project implementation scheme can be realized by utilizing the influencing factors of levee stability in the project. This method needs the designers and the constructors to participate in the determination of the design scheme and the construction organization plan together, which can give full play to the advantages of technology and engineering practice, and achieve the purpose of reducing the project cost. At the same time, the method can give full play to the linkage and coordination of design and construction, coordinate the implementation sequence of the whole project, and control the key points and key points of construction of each section of embankment. It fully embodies the close coordination and unity between the design scheme and the construction organization, which is of great significance for the control of engineering quality and the reduction of engineering risks. A reasonable and feasible control method is put forward from the aspects of construction rate, construction procedure, closure of the Longkou, monitoring of the dike body and control of the embankment danger. The system embankment stability control method provides a theoretical support and guidance method for the construction organization and construction quality control of the soft foundation embankment, which is helpful for the construction side to effectively control the levee stability during the construction process, thus reducing the engineering losses caused by the embankment deformation.
