【摘要】：施工监控是确保工程结构在施工和使用阶段完美体现设计思路的一种手段。它主要包括两方面的内容：施工监测和施工控制。施工监测不但可以保证工程施工中的安全而且施工监测的结果也为施工控制提供数据。而施工控制就是在施工全过程进行有效的控制，保证工程施工满足设计要求。近几年来，施工监控广泛应用于桥梁、边坡、隧道与大坝工程。但是在码头方面，施工监控运用得还相对较少。文章以某架空斜坡码头工程中通用泊位为依托，研究了架空斜坡码头的施工监控的内容和方法，并利用有限元数值模拟，通过对土体的强度折减，研究架空斜坡码头施工过程中施工控制的关键点，为架空斜坡码头设计施工提供参考。论文主要研究内容及结论如下：（1）介绍了控制论的观点、斜坡码头的施工控制及施工控制的影响因素。研究了斜坡码头施工控制系统以及施工控制过程模拟分析方法和施工控制结构分析方法。（2）研究了斜坡码头施工监测系统的建立，包括建立的理论依据、建立的一般方法、建立的一般原则和建立的目的，提出突破观点并介绍其在监测系统中的应用。研究了斜坡码头施工监测的方法与监测的内容，并根据监测的内容简单介绍了施工监测的仪器。（3）考虑桩与岩土体的相互作用型式，，利用有限元强度折减法进行结构稳定分析，对架空斜坡码头施工的每一个施工过程进行模拟分析，以岸坡水平位移与沉降，桩基水平位移以及挡土墙、轨道梁的水平位移与沉降为基点，找出每个施工阶段的突破口，并对其进行重点监测与控制。（4）对基于监测数据处理的斜坡码头预警控制进行研究，包括施工监测数据误差分析、施工监测信息的预报预警，并介绍对监测数据如何处理和预测的几种方法。
[Abstract]:Construction monitoring is a means to ensure the perfect embodiment of design ideas in the construction and use stages of engineering structures. It mainly includes two aspects: construction monitoring and construction control. Construction monitoring can not only ensure the construction of the project. And the results of construction monitoring also provide data for construction control. Construction control is effective control throughout the construction process. In recent years, construction monitoring has been widely used in bridge, slope, tunnel and dam projects. Based on the general berth of an elevated slope wharf project, this paper studies the contents and methods of the construction monitoring of the elevated slope wharf, and makes use of the finite element numerical simulation to reduce the strength of the soil. The key points of construction control in the construction process of elevated slope wharf are studied in order to provide reference for the design and construction of elevated slope wharf. The main contents and conclusions of this paper are as follows:. This paper introduces the viewpoint of cybernetics, the construction control of sloping wharf and the influencing factors of construction control, and studies the construction control system of sloping wharf, the simulation analysis method of construction control process and the analysis method of construction control structure. (2) the establishment of the monitoring system for the construction of sloping wharves is studied, including the theoretical basis, the general methods, the general principles and the purposes of the establishment. This paper puts forward a breakthrough point of view and introduces its application in the monitoring system, studies the methods and contents of the construction monitoring of the slope wharf, and simply introduces the construction monitoring instruments according to the monitoring contents. Considering the interaction between pile and rock and soil, the structural stability analysis is carried out by using the finite element strength reduction method, and each construction process of the elevated slope wharf is simulated and analyzed, and the horizontal displacement and settlement of the bank slope are taken into account. The horizontal displacement of pile foundation and the horizontal displacement and settlement of retaining wall and track beam are taken as the base points to find out the breakthrough of each construction stage and to monitor and control it emphatically. 4) A study on the early-warning control of slope wharf based on monitoring data processing is carried out, including error analysis of construction monitoring data, prediction and early warning of construction monitoring information, and several methods to deal with and predict monitoring data.
