摘要:
桁架式结构因可提供较大的抗弯刚度，常常是大跨度结构的首选。基坑工程的围护桩是一种需要提供较大抗弯刚度用于承受横向力的受弯构件，桁架结构则是一种最合理的选择。液压高频振动锤可以提供较高的振动频率和激振力可确保在软土、砂砾和卵石层中将装配好的长方形空间桁架振动沉入地基中，使钢桁架桩在软土基坑中得以实施。与现今流行的支护结构相比，钢桁架桩可回收满足节能环保要求，结构受力明确，构件可在工厂进行标准化制作现场拼装，其质量可控，施工工期短，同时还可重复使用基坑监测测试原件。因此具有较高的经济与社会效益。
Abstract:
Truss structures usually serve as longspan structures due to their large antibending stiffness. The truss structures are chosen, because the retaining piles of foundation pit engineering require flexural members that can provide large antibending stiffness and bear horizontal force. But it is difficult to construct the truss structures before the excavation of the basement and to ensure that the truss structures only bear nodal loads. Highfrequency hydraulic vibration hammers can provide high vibration frequency and vibration force for sinking the assembled rectangular space truss into the soft soil, gravel and pebble bed to complete the steel truss piles construction. Compared with the traditional supporting structures, the steel truss piles can be recycled and meet the requirement of energy conservation and environment protection. The results show that the stresses of the structures are definite, that the quality of the steel truss structures can be controlled with short construction period, and that the test components in the foundation monitoring can be recycled.
