    摘要:

    为实现对杂填土与软土地基互嵌过程的实时沉降分析,探究软土粗颗粒含量变化对互嵌沉降和软土固结沉降的作用,借助自主研制的杂填土与软土互嵌试验仪,通过室内试验定量区分互嵌沉降和软土固结沉降,设计正交试验组对照分析2种粒径杂填土颗粒(5、10 mm)与5种粗颗粒含量软土(0、3%、6%、9%、12%)在一定荷载下的沉降发展规律,总结总沉降、互嵌沉降、软土固结沉降的最终沉降量和瞬时沉降量的差异。试验结果表明:软土中存在粗颗粒时,总沉降和互嵌沉降在各阶段均较无粗颗粒情况下增长量更大且发展更快,在粗颗粒含量6%时总沉降和互嵌沉降有极大值,粗颗粒含量对软土固结沉降的影响并不明显。

    Abstract:

    In order to realize the real-time settlement analysis of interlaction process between miscellaneous fill and soft soil foundation and explore the effect of coarse particle content of soft soil on the interbedded settlement and the consolidation settlement of soft soil, with the help of self-developed interbedded test instrument of miscellaneous fill and soft soil, the interbedded settlement and consolidation settlement of soft soil were quantitatively distinguished through laboratory tests. Orthogonal experimental groups were designed to analyze the settlement development rule of two kinds of miscellaneous fill particles (5 mm, 10 mm) and five kinds of coarse particle content soft soil (0, 3%, 6%, 9%, 12%) under a certain load, and to summarize the differences of final settlement and instantaneous settlement of total settlement, interbedded settlement, and consolidation settlement of soft soil. The experimental results show that when coarse particles exist in soft soil, the total settlement and interbedded settlement increases more and develops faster than that those without coarse particles in each stage, and the total settlement and interbedded settlement reach a maximum value when coarse particles content is 6%. Besides, the influence of the coarse particles content on consolidation settlement of soft soil is not obvious.
