⛄ 内容介绍

随着综合国力迅速提升,我国进行了大规模的公路网络建设,兴建了数以万计的公路桥梁,为整个经济社会的可持续发展提供了有力支撑。然而,国内外历次大地震中有大量公路桥梁发生破坏,这极大地降低了公路交通的通行能力,严重阻碍应急救援工作和城市日常生活。我国是遭受地震灾害最多的国家之一,因此,在我国开展公路桥梁地震易损性研究具有重要的现实意义。本文在对汶川地震公路桥梁调查数据深度挖掘整理和全面归纳总结之基础上,采用多种方法比较系统地研究了当代公路桥梁的地震易损性,还开展了基于公路桥梁震害评定地震烈度的研究,旨在更好地服务于公路桥梁的震害预测和损失评估、震后可恢复性研究、交通系统的地震风险分析,以及应急救灾决策的制定和完善抗震设计理论等工作,从而达到减轻桥梁震害和提高救援效率之目的。

⛄ 部分代码

function varargout = zhenhai_quxian(varargin)

% ZHENHAI_QUXIAN MATLAB code for zhenhai_quxian.fig

%      ZHENHAI_QUXIAN, by itself, creates a new ZHENHAI_QUXIAN or raises the existing

%      singleton*.

%

%      H = ZHENHAI_QUXIAN returns the handle to a new ZHENHAI_QUXIAN or the handle to

%      the existing singleton*.

%

%      ZHENHAI_QUXIAN('CALLBACK',hObject,eventData,handles,...) calls the local

%      function named CALLBACK in ZHENHAI_QUXIAN.M with the given input arguments.

%

%      ZHENHAI_QUXIAN('Property','Value',...) creates a new ZHENHAI_QUXIAN or raises the

%      existing singleton*.  Starting from the left, property value pairs are

%      applied to the GUI before zhenhai_quxian_OpeningFcn gets called.  An

%      unrecognized property name or invalid value makes property application

%      stop.  All inputs are passed to zhenhai_quxian_OpeningFcn via varargin.

%

%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one

%      instance to run (singleton)".
