The results showed that when considering only the value of permeability of each soil type and intensity rain which is equal to the permeability of the soil, the soil with high permeability Ks = 10-4 M / s will be changed, the reduction of safety ratio (F.S.) more quickly than the soil permeability medium Ks. = 10-5 M / s and the soil permeability low Ks = 10-6 M / s, respectively. And found that the intensity of rain with the modulus of soil infiltration capacity very much will have a change of อัตราส่วนความปลอดภัย less and change slowly and considering the intensity of rain gradually increased จนใกล้เคียง or higher, the infiltration of each soil found safety ratio is more lower. Down by considering the time interval (T < = 24 hours), it was found that the safety factor will be reduced rapidly. When considering the changing slope slope slope slope start found with เอียงที่ lower ratio is higher than the default security Or said that the properties of the soil. (the permeability of soil water. And the rain intensity is the main factor that affect the stability of soil slope due to rainfall in parts of the characteristics of soil slope (the tilt angle and the thickness of the soil). A minor factor affecting the stability of slope.The direct shear test of soil moisture, it was found that the shear strength of the soil are แปรผกผันกับ saturation levels of water in the soil. The values, beliefs, and tight effectiveness decreased clearly when the humidity is increased and the ค่ามุม internal friction effectiveness is decreasing according to the humidity increased significantly as well.Luckily, they can contact the station coast defense units in America tea time state of Massachusetts, which at that time, the station warrant officer Daniel.
