排桩与抗滑桩在基坑与边坡支护中的选择及应用

Selection and Application of Row Pile and Anti-Slide Pile in Foundation Pit and Slope Supports

选取两个不同案例,从基坑支护和边坡支护角度,对比分析了抗滑桩和排桩的选择和运用。通过分析,当深度较浅时,抗滑桩支护在经济上具有一定的优势,当深度较深时,排桩支护在经济上具有一定的优势。基坑或者边坡支护时,在开挖受外界条件限制,无法采用放坡型式,采用排桩或抗滑桩支护时,可通过两种方式对比进行分析,多种支护方式论证,选取最优方案进行支护设计。

Based on two different cases,the selection and application of anti-slide pile and row pile are analyzed and compared in terms of foundation pit and slope supports.The results show that anti-slide pile support costs less subject to shallow area,but row pile support has certain advantages in construction cost subject to deep area.Being restricted by external conditions,neither foundation pit support nor slope support can be done as per sloping pattern,The selection of row pile or anti-slide pile shall base on comparison,analysis,and argument so as to produce an optimum plan.
