钢筋混凝土灌注桩闸基设计是六十年代以来水闸设计的一个新的课题。由于水闸受力条件和结构要求的特殊性,目前还没有一套完整的设计方法。本文通过实际工程的观测资料分析,提出了灌注桩闸基设计的一些看法,并提出了桩土分担垂直荷载的数值解。这一方法可以更近似地计算闸基各桩的受力情况,使桩和底板的计算更趋合理。此法还可推广到闸基在同一底板下,采用不同桩长的分析计算,使布桩更为合理,从而达到节约工程投资的目的。
The design of the sluice foundation of reinforced concrete cast-in-place piles is a new topic in the sluice design since the 1960s. Due to the special conditions of force conditions and structural requirements of sluice gates, there is currently no complete set of design methods. In this paper, through the analysis of the actual engineering observation data, some views of the design of the pile foundation of the cast-in-place pile are put forward, and the numerical solution of the vertical load of the pile and soil is presented. This method can calculate the force conditions of each pile of the sluice base more approximately, and make the calculation of piles and floors more reasonable. This method can also be extended to the base of the same base, using different lengths of the analysis and calculation, so that the pile is more reasonable, so as to achieve the purpose of saving engineering investment.
