本文按照固结理论计算砂井的原理,作出了一整套诺模图,从而能用图解法很方便地确定砂井的设计方案,不必进行繁琐的计算工作;还能很方便地按不同的砂井方案获得最佳设计。特别是在厚度不等的软土地基中,当要求在同一时间内达到相同的固结度时,用一般的方法必须进行大量的计算,而用本文的图解法则能很方便地得出符合要求的最佳砂井设计方案。最后还给出了例题。 In this paper, according to the consolidation theory to calculate the principle of sand wells, a set of nomograms is made, which can be used to determine the design of sand wells graphically, without the need for tedious calculations; it is also very convenient to press different sands. Well plan gets the best design. Especially in soft soils with different thicknesses, when it is required to reach the same degree of consolidation at the same time, a large number of calculations must be performed by the general method, and the graphic method of this paper can be easily used to meet the requirements. The best sand design plan. Finally, examples are given.
