摘　　要：基桩的水平承载力受桩侧土性质、桩身强度、桩顶约束等因素影响。在进行单桩水平承载力试验时,降低上述因素对单桩水平承载力的影响,准确选取单桩极限受力工况,对桩基水平承载力的验收具有重要意义。本文通过基桩静载试验,分析基桩在不同性质桩侧土、不同桩顶约束及不同受力方向等条件下的水平承载力试验值,对水平承载力的影响因素进行了归纳总结。The lateral bearing capacity of a pile is affected by factors such as the nature of the soil around the pile,the strength of the pile body and the constraints of the pile top.When carrying out the lateral static loading test,reducing the influence of the above factors on the lateral bearing capacity and accurately selecting the ultimate load condition of a single pile is of great significance to evaluate the lateral bearing capacity of the pile foundation.In this paper,through the lateral static loading test,the test value of the lateral bearing capacity of the single pile under the conditions of different types of pile side soil,different pile top constraints and different force directions are analyzed,the influencing factors of lateral bearing capacity are summarized.
