【中文摘要】 为了及时了解大型桥梁地基基础在施工与使用过程中的安全性,本文总结了国内外利用现场监测手段了解与控制大型桥梁地基基础安全性的应用现状,在这个基础上借鉴岩土工程中边坡安全性监控理论的研究成果,结合桥梁地基基础自身在结构、受力与施工上的特殊性,建立了大型桥梁地基基础安全性实时监控体系,并且针对其中的一些具体问题进行了深入研究。稳定性是桥梁地基基础安全性的一个方面,本文在研究安全性的同时结合桥梁地基基础的特点、重点针对稳定性研究。具体而言,本文进行了如下一些研究工作: 1.建立了大型桥梁地基基础安全性实时监控体系。对于监控体系中的监测系统设计理论、信息传输系统设计理论以及建立在理论计算模型、专家知识与工程类比基础上的安全性预测预报理论都进行了详细地研究。 2.针对监控理论中的力学参数反演方法,文中回顾了力学参数反分析的现状,提出了力学参数反分析的智能化系统方法。由于该系统提出了参数灵敏度分析的统一方法,而且在参数灵敏度分析的基础上进行信息选择、目标函数设计与参数反演,因而提高了反演的效率与准确性。 3.由于许多大型桥梁基础坐落在层状岩体上,这些层状岩体中软弱结构面上的力学参数利用常规位移反分析...更多方法一般不能进行有效反演,于是本文在引进宏观应变概念的基础上,提出了一种新的目标函数,利用该目标函数可以有效地提高各个软弱结构面上的力学参数反演精度。 4.利用上述理论方法,详细描述了江阴长江大桥地基基础监控系统的设计,并且利用专家经验与理论分析模型对监测资料进行了分析,较好地预测了锚碇的变位与安全性。  还原水利论文#@7@9F nS#V&l

【英文摘要】 This paper summarized the actuality of how to know and control the safety of foundation under the ground by monitoring in the site at home and abroad, in order to find out the safety of the large-scale bridges' foundation and basement in the course of construction and service period. The monitoring system of bridge foundation and basement is built, making use of the theory of slope monitoring, and integrating the special characteristics of foundation and basement of the bridges in the structure, loading and construction. Some specific problems of this system are discussed too. The works of this paper is as follows in summery:1. The monitoring system of bridge foundation and basement is built. The design theory of monitoring system, information transmitting system and the forecasting theory of safety building on the base of computation models, specialist knowledge and similar engineering are discussed in detail.2. The paper reviewed the status of the back analysis of mechanics parameter...更多s in the monitoring system, and then the FEM-neural network method making use of back analysis of mechanics is put forward. This method improves the efficiency. Because the unitive method of analyzing the sensitivity of parameters is reached in the system, and the information selection, the design of the target functions and the back analysis is applied on the base of the sensitivity of parameters, the system improves the efficiency greatly.3. Many bridges' foundation locates on the layer-to-layer rock and soil, and the mechanics parameters of the weak layer can not be back analyzed by common back analysis methods. A new target function is brought forward on the base of macroscopic strain and the mechanics parameters can be more accurate using this target function.4. The design of monitoring system of Jiangyin Yangtze River Bridge foundation and basement is described in detail, and the inspection data are analyzed by specialist knowledge and theory models and the deformation and stability of anchorage is forecasted in good accuracy.  还原
