从断裂力学理论入手，在连续介质力学的框架下，对高喷灌浆防渗墙进行了静力分析。采用非线性增量有限元法，模拟了整个高喷墙的应力变形特性，提出了其切线弹性模量的计算模型和方法。通过工程实例及室内试验，将理论计算结果与试验结果进行了对比，结果表明，理论值较试验值普遍偏大2％～3％，精度满足工程需要。

Starting from fracture mechanism,under the frame of continuous medium mechanics,static analysis was performed on high pressure jet grouting seepage-proof wall. Adopting non-linear increment finite element method,it stimulated the stress distortion property of the whole HP jet grouting wall,and put forward calculation matrix and method of its tangential flexible modulus. By means of project cases and indoor tests,it made comparison between theoretical calculation results and experimental results,thus this result indicates that the theoretical value is generally around 2%-3% larger than that of test. Precision is in line with project requirements.
