在深基坑支护结构的设计时,仅从现场地质勘察报告中给出的数据,往往不能反映基坑地质情况的真实性,由于深基坑支护结构施工工程技术复杂,涉及范围广,事故频繁,因此在施工过程中应对支护结构本身及周边环境进行监测,通过监测对现场所得的信息进行分析、进行信息反馈、临界报警,以便及时调整设计、改进施工方法,制定应变(或应急)措施保证基坑开挖及结构施工安全,达到动态设计与信息化施工的目的,防止重大工程事故发生。
In the design of bracing structure of deep foundation pit, the data given from the on-site geological survey report often can not reflect the authenticity of the geological conditions of the foundation pit. Due to the complicated technical construction of the deep foundation pit supporting structure and the wide range of issues involved, Therefore, during the construction process, the support structure itself and the surrounding environment should be monitored. Through monitoring, the information collected at the site should be analyzed to provide information feedback and critical alarm in order to timely adjust the design, improve the construction method and make the contingency plan ) Measures to ensure the safety of foundation pit excavation and structural construction to achieve the purpose of dynamic design and informatization construction so as to prevent the occurrence of major construction accidents.
