Safety assessment for buried drainage box culvert under influence of underground connected aisle blasting

Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 2, Pages 191-204 doi: 10.1007/s11709-022-0906-1

Abstract: urban environments is considered to influence the safety and stability of the overlying drainage box culvertThe vibration response evolution law of the buried drainage box culvert under blasting vibration wasThe results reveal that the maximum tensile stress of the box culvert structure was 0.33 MPa.as the water level in the box culvert increased.Based on the relationship between the tensile stress of the box culvert, PPV of the box culvert, and

Experimental study on concrete box culverts in trenches

Baoguo CHEN, Junjie ZHENG, Jie HAN

Frontiers of Structural and Civil Engineering 2009, Volume 3, Issue 1, Pages 73-80 doi: 10.1007/s11709-009-0008-3

Abstract: experiment and numerical simulation were conducted to evaluate the variation of vertical earth pressures on culvertThe result revealed that the soil arch forms when the backfill on the culvert reaches a certain heightThe soil arching effect reduces the stress concentration on the crown of the culvert but it is unstableThe vertical earth pressure on top of the culvert is significantly different from that recommended by
