Research on Construction Control Measures for Deep Excavation Deformation of Buildings in Muddy and Sticky Soil Layers
This article takes a residential area in Xiamen as the research object,and uses on-site monitoring methods to monitor and analyze the deformation law during the construction process of deep foundation pits.The results show that:(1)the groundwater level at each measuring point has a significant decreasing trend,and at the same time,the settlement changes between each measuring point are not significant in the early stage of construction.(2)The horizontal displacement increments of each measuring point are consistent and increase with time.After 200 days,the difference in horizontal displacement increments between measuring points SP1 and SP3 is 8 mm.(3)Within 0-100 days,there is a decreasing trend in the depth of groundwater outside the foundation pit,but the magnitude of the decrease is not significant.(4)By comparing the axial forces of each layer of anchor cables,it is shown that the axial force of the first layer of anchor cables is greater than that of the second layer of anchor cables and greater than that of the third layer of anchor cables.
