摘 要：《公路路基设计规范》中定义如下：“路堤（embankment）：高于原地面的填方路基。路堤在结构上分为上路堤和下路堤，上路堤是指路床以下0.7m厚度范围的填方部分，下路堤是指上路堤以下的填方部分。”68736
而支护在《地球科学词典》中定义则为：“地下硐室开挖后的稳定及施工安全，而采取的支持、加强或被覆围岩的构件或其他措施的总称。采用传统矿山法施工时，支护类型有保留矿柱、架设支架、加固岩石三种。采用新奥法施工时，按支护作用效果可分临时支护和永久支护两类，包括喷锚支护、钢木支撑、混凝土衬砌、注浆支护等多种类型。”

Design of embankment and support for ShenHa Passenger Dedicated Line
Abstract:"Highway subgrade design code" is defined as follows: "embankment (embankment): higher than the original ground fill subgrade.". The embankment is pided into the road embankment and the lower embankment on the structure. The road embankment is the filling part of the 0.7m thickness below the guiding bed, and the lower embankment refers to the filling part below the embankment."
The definition of support in the earth science dictionary is: "the stability of the underground chamber after excavation and construction safety, and taken to support, strengthen or cover the surrounding rock components or other measures collectively.". In traditional mining method, there are three kinds of support types: retaining pillar, erecting support and reinforcing rock. Under the new Austrian tunneling method, the supporting effect can be pided into two types: temporary support and permanent support, including shotcrete anchor support, steel and wood support, concrete lining, grouting support and so on.
