摘要
以河滩相软土为研究对象 ,利用沉降板、测斜管、孔隙水压力计等多种测试仪器 ,选取有代表性的观测断面 ,进行了一年多的沉降与稳定观测。通过观测数据对河滩相软土的沉降规律进行了分析 ,同时推算了河滩相软土的沉降系数ms ,这对今后在河南省河滩相软土地基上修筑高等级公路具有重要的参考价值。
Taking the soft soil on river beach as research object and settlement plates,deflection inclinometer, and piezometer as testing apparatus, the stability and settlement of representative sections of the beach were observed for more than one year. By analysis of the observed data, a settlement regularity was found and its coefficient - m swas calculated. The obtained result it will be of significanace in construction of high-grade highway on the beach soft soil in the future.
