Compaction Characteristics and Proposed Compaction Method of Construction Machinery

为研究施工机械压实特性及建议压实方法,对我国某机场三期扩建工程进行试验分析研究,通过对不同区段下穿沉降监测进行处理分析。选择该机场2#、3#下穿通道试验工点,开展机场道面及结构静应力、动应力的测试及研究工作。研究填土及道面自重荷载,振动压路机振动压实作用下通道侧壁和路基内的静、动土压力特征,以获得科学的实测数据。对现场测试数据进行分析处理,归纳总结振动压路机振动影响深度和范围,结合下穿通道周围土压力理论研究成果,开展相互作用实证研究。

In order to study the compaction characteristics and the proposed compaction method of construction machinery, an airport expansion project Phase III of China is experimentally analyzed and studied. The treatment and analysis are carried out for the settlement monitoring under the different sections. 2 # and 3 # underpass test stations of this airport are selected to carry out the testing and research work of static and dynamic stresses of the airport pavement and structure. The characteristics of static and dynamic earth pressures in the side walls and subgrades of the underpass under the action of the fill and pavement dead load, and the vibration compaction of the vibratory roller are studied to obtain the scientific measured data. The field test data are analyzed and processed. The depth and range of vibration impact of the vibratory roller are summarized. The empirical research on the interaction is carried out according to the theoretical research results of the earth pressure around the underpass.
