摘要
本文以城市闹市区的一深基坑工程变形监测为例,阐述了工程地质概况,指出了主要监测内容及监测点的布置,详细介绍了基坑在开挖过程中各个阶段的应力、应变变化特征,以及周边管线与建筑物沉降的关系,以图表对监测数据的变化规律进行了分析。以期对今后采用钻孔灌注桩作为挡土结构,设置钢筋混凝土作为坑内支撑,采用锚杆支护的类似工程提供借鉴。
Design and construction of a deep foundation pit was given as an example. Expounds the engineering geological survey, pointed out the main monitoring and monitoring points layout, described in detail in excavation of foundation pit during all phases of the stress, strain variation characteristics, as well as surrounding pipelines and buildings settlement, to chart of monitoring data the variation law of analysis. With a view to the future with bored pile as retaining wall, reinforced concrete as a pit support, bolt support to provide reference. some useful conclusions were drawn through the analysis of the measured results . it is helpful for the similar foundation pits.
