Summary:
Based on the Nanjing Yangtze River ultra large diameter mud water shield tunnel project, corresponding tests were conducted by burying surface settlement observation points, inclinometers, soil pressure gauges, and pore water pressure gauges in the starting test section Study the disturbance mechanism, disturbance law, influence range and degree of soil in each stage of slurry balance shield tunneling The correlation between stress disturbance degree and distance was analyzed, and based on this, the significant stress disturbance area of the soil caused by shield tunneling (stress disturbance degree ≥ 5%) was calculated to be 16 meters outside the shield tunnel (approximately twice the tunnel diameter) Establish a mathematical model for the relationship between incision pressure, synchronous grouting pressure, and surface settlement, and further revise the Peck formula to better estimate the surface settlement caused by slurry shield tunneling Exploring measures to reduce soil disturbance based on shield tunneling parameters
Settlement observation data should be promptly organized and properly stored as part of the technical archives of the project. (1) Based on the measurement of benchmark points, each observation point and its successive settlement amount are obtained (settlement observation results table). (2) The location map of observation points drawn based on the floor plan of buildings and structures, and the relationship curve chart between settlement, foundation load, and duration drawn based on settlement observation results (it is required that a curve chart be drawn for each observation point). (3) Calculate the average settlement, relative bending, and relative tilt values of buildings and structures. (4) The plan layout and structural diagram of benchmark points, and all original data for measuring settlement. (5) A settlement observation analysis report based on the above content (which should include a brief explanation of engineering geology and engineering design)
The engineering status is marked by a certain floor (or elevation) for general civil buildings; Industrial buildings are marked with different load stages as status indicators. For each settlement observation, the settlement amount and cumulative settlement amount between adjacent observation points should be checked. If the settlement is too large or uneven, measures should be taken in a timely manner. The numbering of each observation point in the column for other observation points should be consistent with the numbering in the settlement observation diagram.
