文中首先回顾了软弱地基用碎石桩加固后的一些沉降计算方法。这些方法有的过于复杂,有的则不够精确。作者提出沉降模量的概念,和根据天然地基的沉降模量计算复合地基沉降模量的方法,然后用所得沉降模量,按一般分层总和法计算最终沉降量。最后,通过一个工程算例,说明这一方法具有足够的可靠性。 In this paper, we first review some of the settlement calculation methods for the soft foundation reinforced with gravel piles. Some of these methods are too complex, while others are not precise enough. The authors proposed the concept of a settling modulus, and a method for calculating the settlement modulus of a composite foundation based on the settlement modulus of a natural foundation. Then, the resulting settlement modulus was used to calculate the final settlement by a general layered summation method. Finally, an engineering example shows that this method has sufficient reliability.
