Composite pile foundation system capable of eliminating frost heaving and enhancing horizontal bearing capacity
The invention belongs to the technical field of pile foundations in frozen soil areas, and particularly relates to a composite pile foundation system capable of eliminating frost heaving and enhancing horizontal bearing capacity. The influence of frost heaving can be completely eliminated, and meanwhile the horizontal bearing capacity of the pile foundation can be increased. In the northeast region, the length of a single-stand-column support and a pile foundation is often controlled by anti-freezing and anti-pulling stability and horizontal bearing capacity. The influence of frost heaving can be eliminated at the same time, and the horizontal bearing capacity of the pile is increased, so that although the concrete frustum is added, the length of the pile in engineering can be greatly reduced, and the economical efficiency is very good. According to related design experience, for a strong frost heaving area, the buried length of the pile foundation is about 10 m or above; after the reinforced composite pile foundation is adopted, the length of the pile foundation can be shortened to be within 5 m, and the pile length can be saved by more than half. The device is suitable for various working conditions and good in durability, the anti-frost heaving effect is not changed under the action of repeated freezing and thawing, and the tangential frost heaving problem can be solved without any anti-frost heaving material.
本发明属于冻土区桩基础技术领域，具体涉及一种冻胀消除及水平承载力增强型复合桩基础系统。本发明不仅能完全消除冻胀的影响，还能同时增加桩基础的水平承载力。在东北地区的单立柱支架，桩基础的长度往往由抗冻拔稳定性和水平承载力控制。本发明能同时消除冻胀影响，并且增加桩水平承载力，因此虽然增加了混凝土锥台，但是能大大降低工程中桩的长度，经济性非常好。根据相关设计经验，对于强冻胀地区，桩基础入土长度约在10m以上；当采用本发明中的增强型复合桩基础后，桩基础长度可以缩短到5m以内，能节约一半以上的桩长。本发明适用于多种工况，耐久性好，在反复冻融作用下防冻胀效果不变，不用任何防冻胀材料就可解决切向冻胀问题。
