Study on the Scheme Rationality of the Shield Tunnel Crossing Airport
The research on settlement control of shield tunnel under the airport includes the following contents:①Determination of settlement control index under the airport;②Theoretical calculation and numerical analysis of underpass airport runway;③Shield construction measures.The conclusions are as follows:①Combined with the previous engineering experience of shield successfully crossing airport runway,the settlement control value is 10mm.②Through scheme comparison,both conventional single-hole single-line small-diameter shield and single-hole double-line large-diameter shield can meet the requirements of runway settlement.
