旺滿模具系列;路基由填筑或開挖而形成的直接支承軌道的結(jié)構(gòu)。也叫做線路下部結(jié)構(gòu)。路基與橋梁、隧道相連,共同構(gòu)成一條線路。路基依其所處的地形條件不同,有兩種基本形式:路堤和路塹,俗稱填方和挖方。
The structure of directly supporting track formed by filling or excavation of subgrade. Also known as line substructure. The roadbed is connected with bridges and tunnels to form a line. There are two basic forms of subgrade according to its topographic conditi: embankment and cutting, commonly known as filling and excavation.
