In shield construction. the limit support pressure of the tunnel face has an important influence on ground settlement and construction safety. In this study. MIDAS GTS NX software was used to conduct a series of three-dimensional finite element simulations to investigate variations in excavation face support pressure under different layered ground conditions. https://safeersappliancers.shop/product-category/newworld-vision-90g-freestanding-b-a-rated-gas-range-cooker-black-90cm-444444209/
