公路工程中湿陷性黄土地质特性及其路基处理技术

在我国的西部,尤其是西北地区修筑公路时,不可避免地会遭遇到大范围的黄土路基,而这其中大部分是具有湿陷性的黄土.因此,必须充分掌握湿陷性黄土的工程地质性质,在施工中对湿陷性黄土进行相应的工程处理.以具体工程为背景,介绍了湿陷性黄土的工程处理措施,使其能够满足设计的各项要求,保证公路工程施工和运营阶段的质量.

Geological Features and Subgrade Treatment Technology of Collapsible Loess in Highway Engineering

In the northwest region of our country, especially during highway construction in northwest region, a wide range of loess roadbed will be inevitably encountered most of which are the collapsible loess. Therefore, we must fully grasp the engineering geological properties of collapsible loess and make corresponding engineering treatment to collapsible loess during construction. Based on practical engineering, collapsible loess treatment technology has been introduced to meet designing requirements and to ensure the quality of highway engineering in construction and operation stages.
