h型抗滑桩是近些年逐渐发展而提出的一种新型防护结构，由于系梁的作用，将前后排桩连接成一个刚架空间结构。

In recent years , h-type anti-slide pile of new protective structure is gradually developed , Because of the beam action , The front and back row piles are connected into a frame structure .

其次，采用标准K&ε紊流模型和追踪自由水面的VOF方法对涌潮冲击排桩式丁坝进行了数值模拟；

Secondly , the standard k - ε turbulence model and VOF for surface tracking are applied to numerical simulation of the bore against the sheet-pile groin .

本文主要依据现有排桩的理论，应用有限元ANSYS确定合适的模拟单元，模拟多支点排桩围护结构，考虑支撑反力和结构的变形随开挖过程的变化。

The article mainly on the basis of row piles theory , apply finite element analysis software ANSYS to select proper simulation element , simulate structure of multi-pivots row piles , consider the change of sustain react and structure deformation during the excavation .

南锚碇基础深基坑支护采用了钻孔灌注桩排桩加多道支撑挡土，2m厚冻土薄壁隔水的新型设计和施工工艺，称为排桩冻结法。

Filling piles and multilayer support and new design and execution technique of 2-m thick frozen soil thin wall water gushing are adopted in South Anchor Cushion Foundation Pit , namely the freezing method of row piles .

基坑深度大于5m，一般采用排桩支护结构加一道或二道内支撑的支护型式。

If the depth of foundation pit is more than five meters , the usual measure is to adapt the displacement pile supports and protects the structure with one or two layers of supports and protects the structure .

s>8d时，门架空间效应也差，联系梁起拉杆作用，前后排桩距的合理范围为4d～8d。

When s > the space effect of the portal frame is also poor with a tie beam acting as a tie bar . The rational range of the distance between two rows is 4d ~ 8d .
