中文摘要摘要：随着城市建设的发展，各地市区中心地带的地价日趋昂贵，向空中求发展、向地下深层要土地便成了建筑商追求经济效益的常用手段。在深圳、广州、东莞等地基坑施工的开挖深度越来越深，从最初的四到八米发展到目前最深已达二十多米。由于地下土体性质、荷载条件、施工环境的复杂性，单单根据地质勘察资料和室内土工试验参数来确定设计和施工方案，往往含有许多不确定因素，尤其是对于复杂的大中型工程或环境要求严格的项目，对在施工过程中引发的土体性状、环境、邻近建筑物、地下设施变化的监测已成了工程建设必不可少的重要环节。当前，基坑监测与工程的设计、施工同被列为深基坑工程质量保证的三大基本要素。基坑监测必然成为深基坑质量、安全保证的关键，是工程建设必不可少的重要环节。关键词：深基坑；基坑监测；时效性；位移；沉降 随差高层建筑高度不断升高,要求地下建筑基础埋深也越来越深,深基坑支护技术在全国不同地区、不同的地质条件下取得了不少成功的经验。基坑监测是深基坑变形观测的主要手段，主要进行基坑的位移、沉降，锚索应力等的观测为基坑质量、安全及时提供了有效的参考数据，更有利于保证基坑质量和安全。iABSTRACTTitle: Application of foundation pit monitoring technology in deep foundation pitABSTRACT: With the development of urban construction, the price of land in all the urban centers has become increasingly expensive. Seeking more space in the air and to the deeper underground has become the builder’s common means of pursuing economic benefit. In Shenzhen, Guangzhou, Dongguan and other places, the excavation of the depth of foundation pit is becoming deeper and deeper, from the initial 4-8 meters to more than 20 meters now. Due to the nature of the underground soil, loading conditions, the complexity of the construction environment, there are often many uncertainties while choosing the programs of design and construction solely based on the information of geological survey and the parameters of geotechnical test, especially to those large and medium-sized complex constructions...
