摘要 花岗岩系为主的侵入岩全风化物,是一种具有特殊物理力学特性的特殊土,遇水具有崩解性,用作路基填料时,雨季易发生压缩变形、边坡冲刷等病害。通过室内试验研究了花岗岩系全风化物及其物理改良填料的工程性质,并在某高速铁路进行了现场填筑试验。试验结果表明,全风化物改良填料的物理力学性能能满足高速铁路路基工程的要求。 The completely weathered material of intrusive rock that are granite series primarily is a kind of special soil having special physical and mechanical properties. It is of water-disintegration and, when used as subgrade filling, subject to compression deformation, slope erosion and other diseases in rainy season. Through indoor tests, the engineering properties of both the completely weathered material of granite series and its filling for physical improvement were studied, with the filling test carried out in the field of a high-speed railway. The test result shows that the physical and mechanical properties of the filling to improve the completely weathered material can meet the requirement of subgrade engineering for high-speed railway.
