摘要］ 阐述在区域性大型断层带的软基处理中运用"水上浮桥"的建模思维方式，根据路基岩土体孔隙率大、松散的特点，采用固结灌浆从挖掘岩土体本身的潜力提高地基承载力，固结灌浆岩土体使准连续配筋混凝土地下筏板基础与摩擦型钢管微桩有机结合，以此提高运煤特重交通路基的整体强度。

In Gastrochilus the lip is semiglobose-saccate with indistinct side-lobes and a much larger mid-lobe, the column is footless and the pollinia are porate, while in Saccolabium the lip is cylindrical-spurred with indistinct side-lobes and a small mid-lobe, the column has a short foot and the pollinia are solid.

盆距兰属的唇瓣为半球形囊状，侧裂片不明显，中裂片甚大；蕊柱无足；花粉团具孔隙。囊唇兰属的唇瓣为圆筒状距形，侧裂片明显，中裂片很小；蕊柱有短足；花粉团实心。

It is revealed that a certain amount of excessive formamide is favorable for preparation of the aerogel with high porosity, while more excessive glycol can deteriorate the formation of nano-porous SiO2 aerogel network. Additionally, the pH value of the reaction system has a strong impact on the microstructure and properties of prepared SiO2 aerogel.
