《南水北调与水利科技》：南水北调中线工程膨胀岩试验研究（何晓民,徐言勇,黄斌,杨洪,徐晗）（摘要）

摘要：在南水北调中线工程新乡潞王坟试验段内选取代表性岩层——强风化粘土岩和泥灰岩的原状样和扰动样，通过一系列土工试验，较全面地研究了膨胀岩的物理力学特性，为南水北调中线工程膨胀岩渠坡段的设计施工提供了科学依据。

Abstract:The representative strong rotten clay stone and marlstone rock samples with undisturbed and disturbed state are selected at the Xinxiang Luwangfen test zone in Middle-Route of the South-to-North Water Transfer Project.Through a series of soil mechanics experimentation the physical and mechanical character of swelling rock has been well studied and supply scientific reference for the design and construction of swelling rock slope in Middle-Route of the South-to-North Water Transfer Project.

Key words:swelling rock;swelling stress;swelling ratio;strength index;initial tangent modulus
