沙漠地区的风积沙在不同的地区其颗粒的组成和相应的化学性质都有着一定的差异性,在具体工程实施过程中其特性也有着非常明显不同,而沙漠地区风积沙工程的特性对路基的稳定性和沉降情况都有着直接的影响。所以在施工实施之前就开展相关的风积沙压实试验对于整个道路的设计、检测以及施工过程都可以起到一定的帮助。鉴于此,本文先介绍了工程的概况及实施中的重难点,然后对风积沙颗粒级配和风积沙压实特性试验进行了一定的分析与研究。
Aeolian sand in desert area has different particle composition and corresponding chemical properties in different areas, and its characteristics are also very different during the implementation of specific projects. However, the characteristics of aeolian sand in desert areas Subgrade stability and settlement have a direct impact on the situation. Therefore, it is helpful for the design, testing and construction of the entire road to carry out the relevant compaction test of aeolian sand before construction. In view of this, this article first introduces the general situation of the project and the difficulties in its implementation. Then the compaction characteristics of aeolian sand grading and aeolian sand are analyzed and studied.
