混凝土院的质量控制
混凝土院的质量控制是一项挑战的任务。工程师和承包商依靠经验和成熟的程序和测试标准来验证桩材料的强度和一致性。非破坏性测试有助于揭示在桩铸造期间可能发生的潜在缺陷（在铸造桩的情况下）或运输和安装（在预制桩的情况下）。分享到LinkedIn分享在Facebook上分享在Twitter上分享...阅读更多»混凝土院的质量控制

什么是交叉孔声波测井？
交叉孔声波测井是深度基础的有效无损检测方法。基于混凝土中超声波脉冲速度（UPV）试验的原理开发，测试可以解决长度/直径（即低应变桩完整性测试）的一些实用限制。该测试可用于收集有关不同深度混凝土的质量和完整性的精确信息。超声波探头的某些组合使......阅读更多»什么是交叉孔声波测井？
混凝土基础的无损检测
This article presents a brief review on Non-Destructive Testing of Concrete Foundations. It also discusses how engineers can utilize NDT to assess defects such as cracking and voids, and the deterioration mechanisms such as alkali-silica reactions, and corrosion of steel reinforcement.

风力涡轮机基础的无损检测
在过去十年中，收获风能已经特别兴趣。加拿大约有300个风电场。风力涡轮机结构非常复杂。虽然涡轮机和塔的检查已经非常好，但在评估其基础的质量，完整性和可靠性的文献相对有限。在本文中，我们将审查风力涡轮机基础的非破坏性测试如何帮助工程师...阅读更多»风力涡轮机基础的无损检测
How To Perform Low Strain Pile Integrity Test?
通常通过用轻型手持式锤击撞击桩头并使用运动换能器（即加速度计）耦合来记录桩的响应来执行桩完整性测试（坑）。
桩检测中的实践考虑因素
桩完整性测试（PIT）是一种非破坏性的测试方法，用于评估桩和深层基础的未知长度和完整性。该技术背后的基本概念正在确定由冲击装置（通常，手持锤）引起的绒绒的速度（所需）和力（可选）响应。桩完整性测试最适合长的结构部件，如驱动混凝土桩，铸造混凝土桩，混凝土填充钢管桩，木材桩，......阅读更多»桩检测中的实践考虑因素
桩完整性测试的应用与局限性
Pile Integrity Test can be used to determine the integrity of piles. The method works best for long structural component such as driven concrete piles, cast-in place concrete piles, concrete filled steel pipe piles, timber piles, structural columns. The method works based on measuring and analyzing the velocity (required) and force (optional) response of pile. A hammer (regular or instrumented) is used to impact the pile surface and induce acoustic waves…阅读更多»桩完整性测试的应用与局限性

重用现有桩 - NDT如何提供帮助
Safety, reliability and satisfactory performance of structures require a well-planned maintenance program, as well as remedial actions in short and mid-term. Existing structures that are designed in accordance with older design codes or were built by older construction practices may need to be extensively repaired, rehabilitated, or replaced within the next few years. The remedial actions may include structural and/or foundation upgrade or replacement. Reuse of existing piles and foundations is…阅读更多»重用现有桩 - NDT如何提供帮助
What is Pile Integrity Test ?
Share on linkedin Share on facebook Share on twitter Share on telegram Share on whatsapp Share on email Construction and installation of concrete piles and deep foundations is a challenging task. Problems may occur during the process, which in turn results in defects or anomalies such as: pile formation problems, concrete faults, and reinforcement installation issues. The resulting defects can negatively impact the durability and mechanical performance of the pile.…阅读更多»What is Pile Integrity Test ?
