A method to calculate the displacement of cuttingface of composite soil nailed walls was introduced.
根据复合土钉支护位移产生的原理提出了一种计算复合土钉支护位移的方法。

The method was based on the conception that incremental relief of in-situ stress generated incremental displacement on the cuttingface. A release force was employed to realize the idea.
为表述复合土钉支护增量应力释放引起增量位移的变形原理,文中引入了一种释放力。

The effects of cutting area, contact arc length, the geometry of cuttingface, back dip angle of PDC cutter and rock performance on force of PDC cutter breaking rock were simulated experimentally.
