介绍了某桩基工程的加固实例，包括其加固方案设计和现场动态监测结果。在静载试验中出现单桩承载力不足的情况后，采取了增补钢管桩和底板加厚的方式进行加固，以提高地基基础的整体承载力，减小基础的不均匀沉降。在施工过程中实施了动态监测，具体内容包括孔隙水压力、桩顶反力、桩间土压力、筏板应力和筏板沉降等，以保证建筑物的施工安全并验证加固方案的可靠性。监测结果表明，各项监测指标逐渐趋于稳定，监测结果基本符合设计预期，加固方案合理可行。
介紹瞭某樁基工程的加固實例，包括其加固方案設計和現場動態鑑測結果。在靜載試驗中齣現單樁承載力不足的情況後，採取瞭增補鋼管樁和底闆加厚的方式進行加固，以提高地基基礎的整體承載力，減小基礎的不均勻沉降。在施工過程中實施瞭動態鑑測，具體內容包括孔隙水壓力、樁頂反力、樁間土壓力、筏闆應力和筏闆沉降等，以保證建築物的施工安全併驗證加固方案的可靠性。鑑測結果錶明，各項鑑測指標逐漸趨于穩定，鑑測結果基本符閤設計預期，加固方案閤理可行。

In this paper,the reinforcement design of a pile foundation project is introduced including rein-forcement design and site dynamic monitoring results.After the inadequate bearing capacity situation of piles occurred in the load experiment,measures of steel pipe pile supplement and thickening bottom plate are taken for reinforcement.As the layout of reinforcement has been carried out,bearing capacity of the foundation is improved while the uneven settlement is decreased.Finally,dynamic monitoring on pore water pressure,load of piles,soil pressure,internal forces and settlement of the raft is conducted during the construction.Hence, safety in construction is ensured and the reliability of reinforcement layout is verified.The monitoring data are tending towards stability and matching with desired consequences.It also indicates the layout of reinforcement is reasonable and practicable.
