九曲河水利枢纽地质均为长江冲积平原,由长江泥沙沉积而成,因而具有固结差,土质软,砂性较高等特点。本文分析了在高水位复杂地基振动沉管灌注桩施工中常见的桩身缩颈、断桩、吊脚桩等缺陷形成原因,有针对性地采取了降水处理、消除上下土层条件不同对成桩质量的影响及解决拔管过快问题、消除桩间距过小对成桩质量的影响、配料处理等有效措施,处理措施简便,经济实用,质量有保证,较大地提高了振动沉管灌注桩的优良率。

The Jiuqu River water conservancy geology for Yangtze River alluvial plain, the Yangtze River
sediment deposition and consolidation, which has poor soil soft, sandy higher. This paper analyzes the causes of common pile complex foundation in the high water level vibration cast-in-place pile in construction of necking,broken pile, suspending pile defects have been taken for treatment, eliminate the soil under rainfall conditions of different influence on the pile quality and solve the problem, extubation too fast and effective measures to eliminate the pile the spacing is too small, the influence of the quality of pile batching processing, treatment is simple, economical and practical, quality assurance, greatly improve the excellent rate of vibration cast-inplace pile.
