地震之后伴随的余震在地震诱发滑坡灾害中起着重要作用。主震中已对岩体造成了不同程度的损伤,这使得余震过程中岩体裂纹进一步发展和相互交互贯通过程更复杂。为了探究地震波荷载对类岩石试样破裂失稳过程的影响,通过采用基于颗粒元黏结模型(bonded-particle model, BPM)的数值方法,研究了在两个正交方向上循环地震波加载作用下的波传播规律和裂纹扩展过程。结果表明,由于计算试样尺寸(76 mm × 152 mm)远小于地震波纵波波长,试样内未观察到波的透射和反射现象;加载产生的裂纹均为微张拉裂纹,重复轴向地震波加载不能使微张拉裂纹进一步扩展;只有当加载方向由轴向变为侧向,再由侧向变为轴向时,裂纹才会进一步扩展并最终导致试样破坏。本文揭示了在地震波反射作用及余震作用下,大量滑坡灾害发生的内在机理。

Effect of nitrogen on mixed culture PHA production was reconsidered. Enrichment history of PHA accumulating culture was discussed. Higher PHA content and biomass growth were achieved in presence of nitrogen. Enrichment strategy toward higher PHA accumulation was investigated. Microbial community succession in PHA accumulation phase was investigated.
