摘要
夹层结构是一种力学性能优越的承载结构，它可以充分发挥材料的作用，做到物尽其利，达到节约钢材的效果。这里将此理论与矿井安全支护相结合，介绍两项可大量节约优质低合金钢的支护构件。
Sandwich structure is a bearing structure with excellent mechanics performance,which can fully display material function, ensuring materails maximum utilization,achieving the result of steel saving.This paper, combining the sandwich theory with the shaft safety supports, .introduces two supporting structures which can save lot ofexcellent low alloy steel.
