摘要:
本文以成绵乐客运专线悦来乡大桥(DK 281+080.3处)0号桥台锥坡垮塌病害为工程对象,通过对锥坡稳定性及垮塌原因的分析,提出了雨季以混凝土填补空洞及大锚杆+喷锚网临时加固桥台锥坡、旱季以翼缘桩永久加固桥台锥坡的永临结合加固措施。结果表明,采用永临结合的加固措施能有效消除高陡桥台锥坡的安全隐患,保障高速铁路的正常运营。
Abstract:
Taking the collapse disease of the truncated conical slope of No. 0 abutment of Yuelaixiang Bridge (at DK 281+080.3) on Chengdu-Mianyang-Leshan Passenger Dedicated Line as the engineering object, through the analysis of the stability of truncated conical slopes and the causes of collapse, this paper puts forward the measures of temporary reinforcement of truncated conical slopes of abutment with concrete in the rainy season, temporary reinforcement of truncated conical slopes of abutment with big bolt+shotcrete anchor net and permanent reinforcement of cone slope of abutment with flange pile in the dry season. The results show that the reinforcement measures combining permanent and temporary works can effectively eliminate the hidden dangers of the truncated conical slopes of abutments on high and steep slopes and ensure the normal operation of high-speed railways.
