文章在紫坪铺水库左岸场内重载公路路肩挡土墙震害调查分析基础上,得出高烈度地震区提出岩土工程稳定性分析需要考虑局部场地条件的影响、Ⅷ度以上高烈度地震区的高挡墙应适当考虑提高地震放大系数、挡土墙材料应改为片石混凝土或混凝土等观点。在总结分析工程建设的抗震经验和教训基础上,对今后工程的抗震设计及抗震设防标准的修编提出一些探索性意见。
Based on the investigation and analysis of the seismic damage of the shouldered retaining walls on the left bank of Zipingpu Reservoir, it is concluded that the geotechnical stability analysis proposed in the seismic zone requires the consideration of local site conditions. The high retaining wall in the area should give due consideration to increasing the amplification factor of the earthquakes and the retaining wall material should be changed to the perspective of slaty concrete or concrete. On the basis of summarizing and analyzing earthquake-resistant experience and lessons learned in engineering construction, this paper puts forward some exploratory opinions on the seismic design of future projects and the revision of seismic fortification standards.
