新加坡海工工程沉桩贯入度控制的研究与应用

在桩基工程锤击沉桩施工中,打桩锤的大小、桩基结构的可打性等均与沉桩贯入度有关。为确保锤击沉桩的质量,需要对沉桩贯入度控制进行研究与应用。通过新加坡樟宜海军基地四期码头等工程实例,对锤击沉桩中的贯入度计算方法、现场控制方法及验证与改进措施等进行了探讨。并通过分析证明:无论是国内还是国外,在桩基工程施工时,贯入度的动力计算为合理选择打桩锤、合理控制沉桩贯入度提供了直接有效的方法。

Piling penetration control in Singapore marine works

In piling works, both the type of the piling hammer and the driven ability of the pile are related to the penetration. Thus the penetration controlling shall be studied. Taking the Piers, Wharves & Ancillary Work at Changi East-Phase 4, Singapore as an example, we study the penetration calculations and controlling methods for pile driving and the discuss the verification and improvement measures. The analyzing result shows that the penetration calculation in piling construction provides a direct and effective method for reasonable selection of driving hammer and control of penetration both at home and abroad.
