It has been clear for some time that the groundwater level at Giza is rising. Pools were forming in front of the Valley Temple of Khafre, and people were worried that this might endanger the Sphinx and its temples as well. In early 2008, the SCA, in cooperation with Cairo University's Engineering Center for Archaeology and Environment, drilled four boreholes, each 4 inches in diameter and about 20 meters deep, into the bedrock at the base of the Sphinx. A camera lowered into each borehole allowed the engineers to examine the geological configuration of the plateau beneath the Sphinx. In addition, a small well called a piezometer was inserted into each borehole to monitor the underground water level. The investigation revealed that the water came up to about 15.6 meters above sea level, not an immediate threat to the statue, but cause for concern in the long term. I decided that it would be best to go ahead and address this threat before it could become more acute.

吉萨的地下水位呈上升趋势已不是一天两天的事了山谷中哈夫拉庙的前面正在形成一个个水塘，人们担心这样下去会危及狮身人面像和庙宇 2008年初，在开罗大学工程中心的合作下，最高文物委员会着手处理考古和环境方面的问题他们在狮身人面像基座的基岩上钻了四个直径4英寸，深约20米的孔，每个深孔中放入一个摄相机，让工程师们可以检查到狮身人面像下方的高原地质结构此外，把一个称为测压表的管子插入到每个钻孔中，监测地下水位调查显示，目前水位已达海拔15.6米以上，虽还未直接威胁到雕像，但提醒我们要长期关注我决定，最好防患于未然，在问题变得更尖锐之前采取一些措施应对这一威胁

利用地震危险性概率分析方法对大型一等工程－某大型水利枢纽工程所在的场址进行地震危险性分析；该拟建工程场址所在的西昆仑地震带是新疆境内地震活动强度最高、频度最大的地震带，拟建工程坝高库大，为了进行准确的地震危险性分析研究，本研究根据区域地震活动性及地震构造研究成果，确定了地震活动性参数，按照构造类比、历史地震重演原则划分了潜在震源区；在分析了区域地震活动环境和地震构造等因素后，综合评价其对场地地震危险性的影响；根据确定的地震动衰减关系及地震带、潜在震源区的地震活动性参数，应用概率方法计算得出了场地不同概率水平的水平向基岩峰值加速度。

Firstly, radial horizontal component and transverse horizontal component are derived from tri-channel seismic data at the surface and the bedrock in borehole array by back-azimuth decomposition method, and the histories of radial and vertical components are divided into two parts by Sg wave arrived time. Moreover, it is supposed that transverse horizontal components are made up of SH wave, while vertical component and radial horizontal component are constituted by P-SV wave system.
