摘要
本文研究了河南南阳膨胀土的强度特性。研究的内容包括现状强度、长期强度和其他非常规条件下的强度。研究的方法采用室内与现状相结合和宏观与微观相结合的方法,在分析中特别注意土中的裂隙结构面对强度的影响。为规划中的“南水北调”中线工程引水渠道的安全施工与正常运用提供参考,并对工程中应如何取用强度值提出了建议。
This paper deals with the strength characteristics of the swelling soil in the Nanyan Prefecture of Henan Province. Strength under the in situ, long term and other unconventional conditions is studied by combining laboratory with field and marascopic analyses with microscopic one. In analyses, special attention is given to the effect of crevice texture sections in a soil on its strength. It gives a reference to safe construction and normal operation of the diversion canal In the mid-line alternative of diverting water from the Yangtze to the Yellow River. A proposal regarding how to take the strength value in engineering is presented.
