中文摘要：

为了研究坡度角和桩间距对试验的影响,结合水平静载试验的工程实例,利用数值分析的方法进行原型水平静载试验模拟.并依据坡度角影响临界值和桩间距影响临界值将水平承载桩分为两类：第-类为地形平缓地段大间距埋人式抗滑桩,第二类为地形陡峭地段小间距支护桩和抗滑桩.满足小于坡度角影响临界值且大于桩间距影响临界值的第-类水平承载桩桩,可利用相邻桩提供试验反力进行水平静载试验.除了第-类桩外,其余的支护桩和抗滑桩都属于第二类,可用新型反力装置-相邻桩上架设反力钢梁进行水平静载试验.

英文摘要：

Based on the engineering example of horizontal static load test, a numerical method is adopted to simulate prototype horizontal static load test and study the effect of slope angle and pile spacing. According to the critical values of slope angle and pile spacing ,horizontal bearing piles can be divided into two categories. The first one is the embedded slide-resistancepile of large spacing for gentle terrain. The second one is the support pile and slide-resistancepile of small spacing for steep terrain. In the first category,the piles with slope angle smaller than the critical value and spacing larger than the critical value can use adjacent piles to provide reaction force in horizontal static load test. The rest support piles and slide-resistance piles all belong to the second category. The test on them can be conducted with a new reaction apparatus-setting reaction steel beam between adjacent piles.
