随着我国风电行业的大力发展，在钻机无法到达的风机位，如何查明岩体上部覆盖层厚度，划分岩体风化界面是一个重要的技术问题。在河北两个风电场的岩土工程勘察中，针对介质的电磁差异，应用探地雷达方法查明地下岩性分布获得了较好的应用效果；利用地下介质弹性和密度差异，应用瞬态瑞雷波法也可以有效查明地下岩性分层情况；在同一个风机位进行联合勘探试验，结果表明，两种物探方法解释结果与钻孔资料均吻合较好，二者可以相互验证补充，提高了解释精度，为电力岩土工程勘察中综合物探的应用提供了一类实例。

Comparing with the domestic projects, there are many different constraints for the Vacuum-surcharge preloading design of soft sub-grade condition in Vietnam projects, and also there are not any relative available codes or standards to use. Based on the special condition in soil improvement design in Vietnam, the article proposes to supplement the geotechnical investigation and soil test, and give the analysis and control methods of key technique about the design of new horizontal drainage system, clay sealing wall, vacuum system, theory settlement calculation, and the application of monitoring data. Finally, the settlement, degree of consolidation and bearing capacity of the soft soil layer can all meet the requirement in contract after soil improvement.
