摘要

对波纹钢板箱涵壳的周截面变形进行了分析。采用选定壳点的挠度和单位应变作为波纹钢壳变形的度量。这些量是用电感位移计和电阻应变计测量的。研究是在实验室条件下进行的，具体选择了分布式负载的配置。试验采用载荷强度、堆载物厚度和载荷作用在堆载物上的面积作为可变参数。分析了土工格栅与堆载土相互作用对减小壳变形的效果。

Testing the load capacity of a soil-steel box structure

The deformation of the circumferential section of a box culvert shell made of corrugated steel plates is analysed. Deflections and unit strains in selected shell points were adopted as the measure of the deformation of the corrugated steel shell. The quantities were measured using inductive displacement gauges and electric resistance strain gauges. The investigations were carried out in laboratory conditions under specifically selected configurations of a distributed load. Loading intensity, surcharge thickness and the area of load action on the surcharge were adopted as variable test parameters. The effectiveness of the interaction between a geo-grid and the soil in the surcharge in reducing the deformation of the shell was analysed.

期刊介绍： The quarterly journal Roads and Bridges – Drogi i Mosty is published by the Road and Bridge Research Institute since September 2012 as a bilingual English-Polish journal. From 2002 to 2012 the journal was printed under the title Drogi i Mosty. The journal mission is to promote current achievements in science and technology in the field of road and bridge engineering. The journal is intended as a forum of the exchange of innovative concepts and solutions between the researches from different countries. Original scientific and technical papers in the field of civil engineering and related engineering sciences are published. The scope of Roads and Bridges – Drogi i Mosty includes design, construction, maintenance and safe use of roads, bridges, airports and other transportation structures.
