摘要
孔内弹模测试作为一种原位测试手段 ,在深层软质岩石场地中往往因试验压力不够大而导致失败。在杭州市钱江四桥软质基岩工程勘察中 ,使用日本OYO公司的 4 14 9型钻孔弹模仪 。
As an in-situ test means, the borehole elastic modulus tests are often unsuccessful due to unsufficient testing pressure applied to deep soft rock In the engineering investigation of soft rock at Qianjiang No 4 bridge in Hangzhou city, satisfactory results have been obtained by using the 4149 type borehole pressuremeter manufactured by OYO Corporation, Japan
