| 摘 要： | 通过试验分析影响湿陷的因素,并通过数理统计方法建立了黄土状土的含水率、孔隙比、干密度与湿陷系数δs回归方程,揭示了影响因素对黄土状土湿陷性的影响规律。这些规律可用作对延庆规划新城及其周边地区黄土状土的湿陷性进行初步的判别,对于掌握黄土状土的湿陷性特征和其后相应浅基础工程、道路工程、线性工程尤其是水工类工程,具有重要意义。

Research on Collapsibility of Loess in Yanqing Planning New Town |

| Abstract: | Based on the experimental analysis of influencing factors of loess collapsibility, and the method of mathematical statistics, this paper establishes the regression equation of the moisture content of loess, dry density of loess and void ratio of loess with coef cient of collapsibility of δs. It reveals the rule of in uence factors on the loess collapsibility, and these rules can be used to discriminate the collapsibility of loess soil in Yanqing and its surrounding areas. It has the important signi cance to study the collapsible characteristics and its corresponding application in the shallow foundation engineering, road engineering, especially in hydraulic engineering. |
