马来西亚槟城(PENANG)某拟建高层住宅采用直径为φ450mm的钻孔灌注桩,要求桩端入岩。该工程桩基于1993年完成。桩基完成之后,由于邻近建筑同类桩基开挖发现有的桩未入岩,工程顾问公司邀请澳大利亚某测桩公司抽测本工程部分桩。但该公司提供的测试结果不能令工程顾问公司信服。因此,无法对桩基质量作出评价,使工程长时间停顿,给业主造成很大的损失。 In a proposed high-rise residential building in PENANG, Malaysia, bored piles with a diameter of φ450mm are required for the entry of rock into the rock. The construction pile was completed in 1993. After completion of the pile foundation, the engineering consultant company invited a measuring pile company in Australia to test some of the piles of the project because some of the piles found in the adjacent pile foundations of adjacent buildings were found not to enter the rock. However, the test results provided by the company could not convince the engineering consultant company. Therefore, it is impossible to evaluate the quality of the pile foundation and cause the project to stop for a long time, causing great losses to the owners.
