分别阐述了几种断桩处理措施的工艺原理及优缺点,结合工程实践,阐述了钻孔灌注桩断桩压浆补强加固处理方法的施工技术要点、加固效果及经济效益,指出钻孔压浆补强加固处理断桩操作简便,既缩短工期,又降低了费用,值得推广。 The principle, advantages and disadvantages of several measures of pile breakage are expounded separately. Combined with the engineering practice, the construction technique, reinforcement effect and economic benefit of grouting pile break grouting reinforcement are expounded. Stabilization of pulp stubbing pile reinforcement is simple, both to shorten the construction period, but also reduce the cost, it is worth promoting.
