因为软土地基的沉降量过大、地基的承载力太小、固结花费的时间偏长等特点,这些都没办法达到公路建造的要求,为了有效改善地基情况、加强地基承载力,提高工程质量,就要采取合适的办法解决问题。碎石桩施工技术术语复合地基法中的主要类型之一,该技术通常使用在公路工程软基加固的施工工作里。该技术是把砂、碎石这些材料展开软土置换,亦或是通过桩振动、挤密这些动能以及缺少加固位置来组建成复合地基,由此来达到地基加固的目标。因为碎石桩可以改善地基情况。减少总体沉降量,此外其优点还包括了加固时间花费少、施工时更为便利的优点,因此在工程软基施工中得到了极大的推广。笔者将结合具体的实际案例,对于碎石桩的情况和公路工程软基加固碎石桩技术展开研究。
Because the settlement of soft ground is too large, the bearing capacity of the foundation is too small, the consolidation time is long and so on, these are no way to meet the requirements of highway construction, in order to effectively improve the foundation, strengthen the foundation bearing capacity and improve engineering Quality, we must take the appropriate approach to solve the problem. Gravel pile construction technology terms One of the main types of composite foundation method, the technology is usually used in highway construction soft foundation reinforcement construction work. The technology is to replace the soft soil with sand and gravel, and to achieve the goal of foundation reinforcement through pile vibration, squeezing these kinetic energy and the lack of reinforcement sites to form a composite foundation. Because gravel piles can improve foundation conditions. Reduce the overall settlement, in addition its advantages include less time to spend reinforcement, construction more convenient advantages, so in the construction of soft foundation has been greatly promoted. The author will combine the specific practical case for the situation of gravel piles and highway engineering soft ground reinforced gravel pile technology research.
