摘要
我国西部地区沙漠分布广泛,富产风积砂.本文通过室内击实试验研究了风积砂的最佳含水量和最大干密度;且通过静载荷试验,对风积砂的压实特性进行了研究.该试验结果将对风积砂的工程应用提供了一定的理论依据.本文还通过试验分析了风积砂与土工格栅的界面摩擦特性,为风积砂在加筋工程中的应用提供了一定的依据.
In West China,there is a great abundance of eolian sand in vest expanses of desert. An analysis is made of the optimal water content and maximal dry density of the eolian sand through a series of hammer tests. Through static load tests,its compactness is also studied. Results of these tests furnish a scientific basis for the use of eolian sand in engineering projects. In addition,tests are made for the analysis of the character of interface friction between eolian sand and geogrids,which offers a good help for the design of eolian sand reinforcement.
