随着建筑设计和施工技术水平的日渐成熟完善,土地资源也日渐减少与人口增长之间日益突出矛盾,高层及超高层建(构)筑物越来越多。为了保证建构筑物的正常使用寿命和建(构)筑物的安全性,并为以后的勘察设计施工提供可靠的资料及相应的沉降参数,建(构)筑物沉降观测的必要性和重要性愈加明显。 With the gradual maturity and perfection of the architectural design and construction technology, the contradiction between land resources and population growth has become increasingly prominent. There are more and more high-rise and super-tall buildings. In order to ensure the normal service life of building structures and the safety of building structures, and provide reliable information and corresponding settlement parameters for future investigation, design and construction, the necessity and importance of building settlement observation More obvious.
