Field testing and numerical analysis were used to study the influence of boulder deep-hole blasting on the vibration of adjacent shaft.The results show that:vibration holes can effectively reduce damage on the retaining pile of foundation pit by boulder blasting;Isolation holes can guarantee the explosion integrity.The blasting vibration speed of shaft can be effectively controlled by increasing blasting area, reducing the distance between holes and reducing the amount of one blasting.Taking the 5 partitions of boulder as an example, the blasting vibration velocity can be controlled within 2 cm/s as the hole spacing was adjusted to 0.5 m×0.4 m and the explosive diameter was adjusted to 32 mm.As a result, the safety of adjacent structures was ensured, and the boulder blasting effect met the requirements of shield tunneling.
