The hy drog eologic co ndi tions along the whole bridge were v ery complex , a nd therefore , the co nst ructio n of i ts foundatio ns under the deep w ater became o ne of the most di fficult point s in the construction of this bridg e. The paper descirbes the method fo r co nst ructing these bridge foundatio ns in the deep wa ter in detail , and ex pounds emphatically the co ntro lling mehods for the key w o rking procedures a nd the measures applied fo r cont rolling the const ruction qualities.
