Problems solved by technology
Shield excavation continues along the planned route. If there is no borehole at the excavation position, the stratum parameters at this position can only refer to the data of nearby boreholes or use statistical indicators, so the stratum parameters cannot be provided continuously and relatively accurately.

The invention relates to a value taking method for shield tunneling stratum parameters. The method comprises the steps that (1) performing investigation datamation, specifically, collecting parametervalues of drill holes in different tunneling positions, collecting stratum information and stratum physical and mechanical index statistical values during tunneling and drilling, and creating a coordinate system of the tunneling positions and the stratum information; 2) tunneling line datamation: establishing a position function of a shield tunneling line direction under a unified reference coordinate system according to a tunnel design size so as to determine position coordinates of a tunneling section in real time; 3) determining a stratum boundary function: establishing a function of a stratum boundary under a unified coordinate system, judging a stratum type, and calculating stratum parameters. For each type of strata, the value taking method of the stratum parameters at the tunnelingposition is established based on the interpolation principle, so that continuous supply of the stratum parameters at the tunneling position is achieved, and stratum data support is provided for shieldtunneling data analysis prediction and informatization construction.
Description
technical field [0001] The invention relates to a calculation method for stratum parameters of shield tunneling, in particular to a value-taking method for shield tunneling stratum parameters. Background technique [0002] The shield machine is tailor-made according to the engineering geological conditions, and the setting of shield tunneling parameters needs to be set according to the physical and mechanical parameters of the formation. The engineering geological survey of the site provides the physical and mechanical parameters of the relevant strata for the line, but these data are generally provided in the unit of boreholes, which are point-like, or uniformly provided in units of site strata, and the data errors are relatively large. [0003] Site engineering geological survey provides formation physical and mechanical parameters, which are generally provided in units of boreholes, or statistical indicators in units of site strata, so these data are point-shaped. Shield...
