| 摘 要： | 红层是一种特殊岩土,具有填筑密实度对含水量很敏感等特点。本文首先介绍了离心试验原理和方法,然后介绍了通过离心模型对采用最佳含水量填筑的、压实度分别为87%、90%、93%、97%的四种红层路堤的模拟,得到沉降与压实度、沉降与加速度、施工期与工后沉降与时间的关系,从而确定路堤填筑施工参数。

| Abstract: | Red mudstone is a special rock-soil, its filling density is sensitive to water content. This paper, first of all, gives an introduction to the principle and method for centrifugal experiment, then presents the relations between settlement and compacted thickness, settlement and acceleration, construction duration and post-construction settlement, and construction duration and time through simulating four kinds of red mudstone embankments with filling and compacted thickness of 87 %, 90 %, 93 % and 97 % by centrifugal model, last determines the filling parameters embankment construction. |

| Keywords: | red layer compacted thickness centrifugal experiment settlement |
