摘要
三峡库区大件运输具有临时性、短期性的特点,大件码头的建设大都采用老码头加固改造的方式。通过对三峡库区现有码头结构特点和库区水文条件的分析,提出用遮帘桩型式的改造方案,并对改造方案的结构稳定性进行了计算分析。遮帘桩型式改造三峡库区大件运输码头,结构稳定性能够满足要求,同时结构对航道的通航能力不产生影响,是一种可以应用到三峡库区及其他山区河流水库大件运输码头改造的方案。
Shipment of large and heavy cargos in the Three Gorges reservoirs is characterized by their provisionality and short-running. In most cases, wharves for handling large and heavy cargos are built by reinforcing and modifying existing wharves. After analyses of the structural features of the existing wharves and the hydrological conditions in the Three Gorges reservoirs, it was proposed that barrier piles should be used to modify the existing wharves and the structural stability of the proposed modification was also calculated and analyzed. The calculations and analyses prove that the structural stability of a wharf modified with the barrier piles for handling large and heavy cargos in the Three Gorges reservoirs can meet the performance requirements and will not produce unfavorable impact upon the traffic of the waterways. Thus modification of existing wharves with barrier piles is an applicable alternative for renovation of wharves in the Three Gorges reservoirs and other reservoirs on rivers in the mountainous regions for handling large and heavy cargos.
