基于GIS开发一款大学WEB移动端的社交系统.docVIP

摘要 近年来，随着经济与科技的发展，互联网进入了高速发展阶段。尤其是近几年智能手机等终端设备的日益普及，使用手机上网的用户增幅显著，移动互联网的应用也日渐丰富多彩，这一现象在高校大学生中尤为普遍。大学生们除了在日常生活中正常的互动交流外，很多时候都是在移动终端上进行交流互动。针对这一现象，开发了一大学生为中心，一GIS为原理开发了一款大学WEB移动端的社交应用。 本应用主要服务于大学生社交的应用。主要有爱分享、找朋友、Hi周末（周末去哪玩）、 伴随着经济和科技的飞速发展，一幢幢高楼大厦如雨后春笋般拔地而起。但随之而来的地基沉降，引起了建筑物的沉降，严重威胁着人们的财产和生命安全。建筑的沉降变形情况如何，直接关系建筑物的使用情况。建筑沉降观测不仅是为保证建筑物的正常使用和安全，还为以后的勘测设计及施工提供可靠的资料及相应的沉降参数，同时也为今后建筑物的结构和地基基础合理设计积累资料。 本系统的意义主要是利用实测沉降资料进行基础沉降预测，采用双曲线法、修正双曲线法、指数曲线法等模型预计电厂建筑的沉降情况，保证电厂的正常运作，从而保证经济发展的命脉。 本系统以C#为开发语言，采用VS2012为开发工具，数据库为Access，ArcEngine控件呈现地图,Surfer绘制等值线图。实现电厂建筑物沉降的预计，预计各个阶段的累积沉降量、沉降速率以及电厂信息的查询、分布情况。 关键词：GIS；建筑物沉降；累计沉降量；ArcEngine;ADO.NET Abstract Accompany with fly of economy and science and technology to soon develop in recent years, a floating many-storied building grows profusely and quickly a sort to rise straight from the ground.But the foundation follow sink to decline, caused sink of building to decline, seriously threaten peoples property and life safety.The sink of building declines to transform how circumstance is and directly relate to the usage circumstance of building.The building sinks to decline to prognosticate not only is for promise building of normal usage and safety, return is hereafter of survey design and construction to provide dependable data and correspond of sink and decline parameter, also in the meantime is aftertime structure and foundation foundation reasonable of the building design backlog data. The meaning of this system is mainly to make use of to actually measure to sink to decline data to carry on foundation to sink to decline an estimate, adoption double the curve method, correction double curve method, index number curve method etc. the model anticipate a sink of power station building to decline a circumstance, promise the normal operation of power station and promise the life vein of economic development thus. This system with C#is develop language, adopt VS2012 in order to develop tool, the database is an Access, the ArcEngine controls a pie
