该方法具有提高抛石体的密实度，减少抛石体后期沉降，施工简单等特点。

This method bears some advantages, e. g. it will make the compactness of rubble-mould raised, prevent posttreatment from sinking, and make the construction, method simplified.

然而在厚度不均的抛石棱体层中进行冲孔灌注桩施工，在我国工程建设史上还不多见。

But, construction of punched cast-in-situ piles in rubble-mound layer of uneven thickness is still rare in China's engineering history.
