Parameters of anticline, which are from seismic and geological sections of the Cizhuya propagation anticline, respectively, give the consistent depth and dip angle of detachment fault at 8.10-8.63 km and 29°-45°.

根据地震剖面的解释及地表资料整理结果，把上述演算结果应用于重庆方斗山地区的茨竹亚背斜的2个剖面中，计算出隐伏滑脱层的深度分别为8.10~8.63 km，证明茨竹亚背斜隐伏主滑脱层发育于寒武系底部。

With this velocity model and broadband records from 5 CDSN stations, we inverted focal mechanisms of Chifeng earthquake on August 16th, 2003 with the "Cut and Paste" method. Then we confirmed focal depth and the source mechanisms by comparing synthetic body waves at teleseismic distance with broadband records of 9 IRIS stations. Our result shows that the best double couple solution of this M w5.2 event is 315°, 64° and 19°for strike, dip and slip angles respectively, the second nodal plane solution is 216°,74°, and 152°. The focal depth is 25±2 km, suggesting that this quake occurred in the lower crust which is much deeper than most continental earthquakes.

我们以此速度结构作为模型，利用中国国家地震台网5个台站的宽频带地震数据，采用CAP方法反演2003年8月16日赤峰地震震源机制解并初步确定震源深度；再利用IRIS 9个台站远震体波数据，通过对比理论计算和观测记录的方法进一步精确确定震源深度并验证反演得到的机制解，得出此次地震矩震级为5.2，震源机制解为：节面I：315°/64°/19°，节面II：216°/74°/152°，震源深度为25±2 km，已深达下地壳。

Result showed that, with the controlled facility, the water storage is about 19×10^3 m^3/km of in the main drainage canal, the groundwater table in farmland is raise about 0.3 to 0.5 m and the crop water use is increased about 50 to 80 mm comparing with the non controlled main drainage canal.

结果表明，单位长度大沟年调蓄水量为1.9×10^4立方公尺/km左右，其影响范围内的农田地下水位较无控制大沟平均抬高约0.3~0.5 m，每年可增加作物对地下水的直接利用量50~80 mm，区域年农田水资源调控总量110 mm左右，约占当地年均降雨量的13%；只要控制合理、管理得当，不会因此而影响排水系统对农田涝渍的有效控制或降低原有排水工程的除涝降渍标准。
