在土钉-排桩复合结构中,土钉的加固机理使软土主动土压力减小,而土钉的锚拉作用又可能使软土产生附加侧压力。
These opposite effects may lead to additional lateral pressure and make active earth pressure of soft soil bigger than the theoretical value.
两种载荷方式钉孔处存在较高的压应力,但主动载荷时应力更高。
High compressive stress was observed near the inlet of pin tract in both groups, but even higher one under the active loading condition.
由于土钉支护的主动支护机理,水的作用就更为明显。
The failure mechanism of stability of soil nailing wall induced by the action of water is also proposed.
