高速公路路基最小填土高度的计算与探讨

Study on highway minimum subgrade filling height

针对平原微丘区高速公路路基多以低填为主、土石方多以借方为主的情况,提出路基填土的高度直接关系到高速公路的安全运营和土石方数量的大小,因此确定路基的最小填土高度显得尤其重要,对路基最小填土高度的计算进行了详细的介绍。

In light of plain area highway subgrade features, such as low-filling orientation, earthwork with debtor as orientation, the paper points out that： subgrade soil-filling height directly determines highway safety operation and earthwork amount. Therefore, it is important to determine minimum subgrade soil-filling height, and finally introduces minimum subgrade soil-filling height computation.
