摘要
供水井桥式滤水管推广应用是近几年的新技术，不少使用者对桥式滤水管的性能指标不十分了解，在选择和下管的过程中出现了不少偏差，导致了桥式滤水管或管井的报废，造成了严重的经济损失。该文从桥式滤水管的性能指标入手，进行了受力分析，提出了桥式滤水管的正确选择和使用方法。
The bridge straine spread and applied in the water well drilling is a new technique in recent years. But some users have not fully understood about the performance and indication of bridge straine and made a lot of declinations in the course of choice and case to lead to the fail of bridge straine or tubed well.Thus, the serious economic losses have been caused. The author has started right in with the performance and indication of bridge straine to carry out the stress analysis, and put forward the correct choice and operation method of bridge straine.
